Editor Commands

original post [1] (Note the post mentions ?SEU, I found ?Editor to be also useful)

  • Type ?Editor on the command line
  • Click on 'Default editor commands' to see the commands
  • Click on the command for more info, including usage

Check LPEX commands.

  1. Note the Short Commands (see following small extract from the text)
/text Find the next occurrence of the specified text. 
-/text Find the specified text searching backwards from the current position. 
'text Find the next occurrence of the specified text.  The search is a case-sensitive search. 
-'text Find the specified text searching backwards from the current position.  The search is a case-sensitive search.

WDSCi vs SEU F15=Browse options

ref [2]

original post [3]

  • To edit the same member, the method most analogous to the SEU F15 browse is Ctrl-2 to split view, 
click on subroutine name in Outline View to position the new view to the subroutine, 
do whatever, 
Ctrl-0 to close the second view.

Note that new views opened this way can all allow editing, and you can have up to 5 views open on a single member, not just 2 as in SEU.

  • To edit/browse a different member, Ctrl-Shift-a (or open using any other method). Then drag the member name tab down or to the right until it turns into an arrow and release. This splits the screen (top/bottom or left right) for editing/browse. Does not work when in maximized mode.
  • Alternately, 
just go to the subroutine by clicking on it in the Outline View, 
do whatever, 
then return to the Exsr by clicking on the line number where the subroutine is used.
  • A third way is to set a quick mark and return to it.
  • A fourth way is to set a named mark and return to it.
  • A fifth way (but the Outline View is easier) is to filter the source by the subroutine name
(either Ctrl-F, enter name, click All, or right click, Selected, Filter selected, 
which can also be set up as a key combo if you like), 
put the cursor on the Exsr or Begsr as you choose, and then Ctrl-W.

Note: If you have 6.0.0.1, you're too far behind - I believe you need 6.0.1.0 or higher to be able to open multiple views on the same member.

Position my cursor to where I need to key additional data. (On IBM rqmts list)

original post [4]

In SEU, when I hit enter, the editor will automatically position my cursor to where I need to key additional data? I know tab moves me to the next input position, but not whether it requires input. And by the time auto syntax checking informs me, I have spent time reading the message, relocating my cursor, etc.

  • There is no way to currently do this. It is on IBM's list of requirements.

Automatic cursor positioning can be configured by choosing 'Preferences' from the 'Window' menu. In version 7, you are looking for Remote Systems -> Remote Systems LPEX Editor -> iSeries Parsers -> ILE RPG

Do I have to use the mouse to copy lines from one member to another?

original post [5]

Standard windows copy/paste keys can be used, along with a few extras provided in LPEX (check the Edit menu for selection options)

To copy X lines,

  • put your cursor is on the first line of the block you want to move,
  • press Home,
  • then hold Shift and press the down arrow X times.
  • Now press Ctrl+C,
  • then Shift+F6 (this is like Alt-Tab in windows, but for LPEX editor tabs) until you get to the target member.
  • Now find the line you want to insert at, and press Ctrl+V.

Another method not mentioned yet is to

  • mark the lines to copy using Alt-L,
  • then copy them into position using Alt-C.

The lines will be inserted beginning with the line after your cursor position. You should also explore the other Select/Selected functions, which are listed under the Edit menu with their keyboard shortcuts.

See list, WDSC_shortcuts.

How can I copy field names in to the member? (On IBM rqmts list)

original post [6]

  • This is on IBM's list of requirements.
  • I added a table to the Table View, I can see all my fields, but can't copy and paste from there.
  • Drag and drop from table view to RS LPEX is currently not available.
  • You can always open the DDS source and copy the names from there.
  • Be sure to have a look at the rectangle select - it may come in handy for this (alt-r, alt-c.)

Return to #TOP


Can I condition page ups and downs by cursor position?

original post [7]

  • Or at least jump the cursor to the top or bottom of the displayed view, then I could roll by line up or down.
  • Keys can be easily remapped to do other things - check the mailing list archives for discussions on this at length.
  • You'll also want to read the reference help for what LPEX actions are available/do (scrollTop, scrollUp come to mind)

Try this from the archives; How to set an Alt + xx key to position the current line to the top or bottom of your source window. [8]

  • I use the alt page up and down keys,
  • I also have alt + T set to put the current line at the top of the editor window.
  • Ctrl+T (v7) will put the line where the cursor is at the top of the screen.

Also check WDSC Workbench for more info on key remapping.

Do I have to continually save my work?

original post [9]

In SEU, when I hit <enter>, I know it has been saved, even if I lose my session.

  • Remote Systems LPEX Editor has an auto-save feature.
  • Default is set to every 5 minutes.
  • Check out Windows>Preferences, Remote Systems>Remote Systems LPEX Editor

I save every PC document after every few lines. Virtually all PC software recognises Ctrl-S as the 'Save' sequence.

Auto Marking Changes to the Source

ref FKOL, 3 January 2007 (CST)

Select Window|Preferences|Remote Systems|Iseries|LPEX Editor Parsers

  • Check the box with text 'Add signature to changed lines'
  • and enter your Change number in the Signature box.
  • Click OK

Now whenever you change a line of source code, the 'signature' will be placed in pos 1-5 of the source line.

How do I shift a block of text left/right?

ref Starbuck5250, 5 November 2007 (CST)

Select the block of text by putting the cursor on the upper left corner of the block. 

Press Alt-R.  
Move the cursor to the lower left corner.  
Press Alt-R again.  
Do NOT use Windows copy/paste (ctrl-c/x/v)  
You now have a block of text selected.
  • An alternate way to select is 
Alt-L (line) 
and then hold down the Shift key while using the cursor keys to continue highlighting lines.
  • You can also Alt-L on the first and last lines of the block.

You can shift it left/right with alt-f7/alt-f8 If you remap the keys, the action is blockShiftLeft and blockShiftRight

  • You can shift it via the menu Edit, Selected>Shift selection
  • You can uppercase or lowercase it with alt-k/alt-i or via the menu
  • You can move it: position the cursor where you want the upper left corner to end up and press alt-m or use the menu
  • You can copy it with alt-c
  • You can delete it with alt-d

Remember that Alt-U de-selects the block.

  • Note the following will shift the entire line of code, not just a section or block.
You can use SEU mode line commands LL and RR typed over the sequence number area.
LLnn will shift left nn columns.

To Print RPG Indented Source

original post [12]

  • You can print using the command line below the editor window
  • press Esc when you are in the source. Or just click in it.
  • Type ? print - you will see all the options.
  • To get the entire source use 
print tokenized off lineNumbers off
  • To print only what you've selected, use
print block tokenized off lineNumbers off
  • If you want line numbers and/or shading of elements, make the obvious changes.
  • The print command works even if the File->Print option is disabled - as it is for indented source.

See SQL HOST variables in OUTLINE view. (is not possible)

original post [14]

  • I've long wished that SQL host variables would be part of the outline.
  • And file references in SQL statements - they CAN be parsed, after all, otherwise they could never be run by the system.
  • So it is not impossible, just not in scope, it seems.

Downloading source to PC to work offline

original post [15]

  • Select all the members that you want to download,
  • right click,
  • select Make available offline.
  • Select Yes to the next dialog box.

WDSC will download all the selected members to a iSeries project (named in my version as the CONNECTIONNAME_WINUSERNAME).

  • You can also travel with this project by exporting it,
  • right click on project name and selecting Export.
  • Then select Project Interchange,check off your project,
  • name a zip file to store it in, click finish.

You can then put the zip on a mem-stick and take it home (if that's what you want to do with your time off).

  • You will need to have WDSCi installed on your home PC.
  • In Iseries Project Navigator you need to Import the zip file, reverse the Export steps above. You may need to create a project. File|New|Iseries Project

Be aware of the issue with Iseries Projects in the RPG source was not being saved tip.

original post [17]

You can also record the key strokes by using the start and stop recording icons ( small squares) on the toolbar.

  • Press the start recording icon, insert your signature once, then stop the recording.
  • Everytime you want to insert the signature,
  • press the Playback recording (green arrow beside the two squares).

RPG source was not being saved

original post [19]

  • A RPG source was not being saved to my source file.

I can see the changes in WDSCi but not in the Iseries source.

  • Another symptom is when debugging I need to select the Listing View as the debugger is finding some old source for the *SOURCE view.
  • I cleared the File Cache and the debug cache.
  • I discovered a work around.
Say the member is PGM001, I renamed it (via WDSCI by right-click on the source and Rename)
to PGM001X, do my changes and save them.  Then I rename the member back to PGM001.
  • But the real problem was in Iseries Projects.
I had previously saved this source in a Project so that I could do work on my home PC. 
When I deleted the member from the Window/Open Perspective/Iseries Project view all worked
as expected.

Error-messages are still showing in the edit view

original post [20]

  • After compiling, getting errors, and fixing them, and recompiling successfully, the error-messages are still showing in the edit view.
  • How to get rid of them with out closing the member
  1. Ctrl+F5,
  2. or either Source>Remove Errors,
  3. or Source>Refresh.
  • Its on IBM's list of requirements to automatically remove these during error list reloads.
  • Remove messages from the source by choosing SOURCE/Remove Messages from the top of the screen.
  • While you have theError List window open,
  1. click on the triangle in the top right corner of the window,
  2. choose Show Severity
  3. and uncheck Information to not show informational messages.
  • From the same menu,
  1. click Messages,
  2. choose Insert Selected Only.

This will only insert the message you click on from the Error List Window into the source, and will remove the previous error message when you choose another from the Error List Window.

Click the X icon in the top left part of the iSeries Error List view. (Note: This closes the error list view, but does not clear any errors inserted in the editor window. However, it is important to remember that the errors are not made a part of the source itself. They are simply shown in the LPEx editor window.)

SQLRPGLE Compiles how to find Compile errors

original post [21]

  • First turn off Batch compiles (see compile Interactively tip)
  • Next select Compile(Prompt) to see the compile Parms
  • Select CRTSQLRPGI
  • Click All Parameters checkbox.
  • Set the 'To source file parm to QSQLSRC in 'your lib' NOT QTEMP.

The compile will retreive the EVENTS file and show messages in the Iseries Error list View.

You can click on the error and the source will be displayed with the cursor positioned on the error, but be careful as to what source member is in the 'Location' column of the Iseries Error List view.

If the QSQLSRC member is listed you need to open the 'real' source to the same position to do the appropriate correction.

Ctrl-L lets you jump directly to a given line, or you can type the line number in the Editor command line and you go directly to the line.

Should you find Compile(Prompt) to be a pain, you could customise the compile command.

  • In Table View, Right Click a Source,Click Compile , Click Work with Compile commands
  • Select CRTSQLRPGI and Click Edit
  • Add TOSRCFILE(&L/QSQLSRC) to the command, this saves you setting this parm all the time.


FWIW

  • I found some notes on SQL Restrictions
  • In WSDC V6 Open the CODE editor
  • Click Help,General Help
  • Enter 'Code Tips SQL in RPG and Cobol' Click GO
  • Click 'CODE Tips and Techniques - SQL in RPG and COBOL '
  • Read 'There are some restrictions you should be aware of:

Within RSE, how to compile Interactively versus Batch

original post [22]

  • Window -> Preferences
  • Remote Systems -> iSeries -> Command execution
There is a compile in batch check box.  Uncheck that because the 
compile still draws from the Batch CPW of the server.

Custom Compile Commands

original post [23]

  • In order to have WDSC automatically bring up the compile error list when you are using custom compile commands,
  • add OPTION(*EVENTF) SRCMBR(&N) to the end of your compile command. This tells WDSC that the command being executed is a compile command. ref: [24]

How to get the error list back into WDSC

  • Make sure that you are setting a *CURLIB. This is very important, because that's how the UI finds the EVFEVENT file generated by the compiler.

Technote 1231854 from ibm.com describes the official IBM help on the subject.

Nazmin adds this: [25]

  • If you are running your compile commands from CL, the Error List View is not automatically opened to populate the errors.
  • However, if you specified an option to generate the events file, say for OPM compiler OPTION(*LSTDBG) or OPTION(*SRCDBG), an event file containing the errors is generated.
  • You can manually open this events file in the Error List view and proceed normally.
  • To locate the events file, look in the target library for the compile command for data file EVFEVENT.
  • If you expand this file, you will see all the events files, with the same name as the source member and type mbr. Right click on this, choose the option to Show in Error List.

Andrew adds this: [26]

  • You can code your own Compiler command, which can then be used to determine which command to run, based on the source member type (you have to write your own code here to retrieve the source type).
  • That will then run the command in question, i.e. CRTSQLCBL, CRTCICSCBL, etc.
  • Your own command has to have a parameter called OPTION, that will accept *EVENTF or *NOEVENTF. The parameter doesn't have to do anything, but it needs to be there.
  • When OPTION(*EVENTF) is specified, WDSC will look in the first 20 bytes of the *LDA. This must contain the library and member for the compiled source, so your compiler front end needs to ensure that the *LDA is correctly populated.
  • Assuming that the *LDA is correct and that your IBM supplied compiler command (called by your front end) has been called with OPTION(*EVENTF) - WDSC will then automatically retrieve the correct event file and switch to that tab in the table view.
  • Depending on your settings, this will also insert the error messages into the source member in the Editor.
  • I spent a fair amount of time going through this, and found the following article invaluable [27] when creating our internal version for WDSC.

FIND

Scan for a date when source lines were changed (like F14 in SEU)

original post [28]

  • You could issue the "locate sequenceText" command (in the command line at the case of the RSE editor or press ESC to enable command line), then invoke it repeatedly from the LPEX command line (UP arrow key, Enter).
  • example locate sequenceText 071201 to 071231
  • You can filter by date. Right-click in the source and you can filter by date. ref [29]

Locate is an Editor command.

Easy Source Upload

original post [34] (This came from the comment about copying source between systems)


  • There are lots of useful RPG sources posted on the net,
  • But , How do I get that source into my source file.

WELL WDSCi is a really simple method to upload the source.

  • Mark and copy the source you found on the net.
  • In RSE use CRTL-Shift-A to open a source member into your favourite library/file. (Member will be created if it does not exist)
  • Paste the source code and save it (CRTL-S is one way to save)
  • Voila the source is now yours!!

The outline view of the RPG (or other) program doesn't show the fields TEXT.

original post [35]

The outline view of the RPG (or other) program doesn't have any way to show the TEXT associated with the field in a file, but:-

  • You can easily open the Field Table View that does.
  • This will open the iSeries Field Table View which gives all the field information.
  1. Right-click on the line with the F-spec
  2. Select the Show fields menu option.


  • To show the properties of fields in files.
  1. Right click on a physical file object in RSE tree view
  2. and select show in table -> fields.


  • If you are using 7.0, you are also able to bring up a Field Table View by highlighting any (PF, LF, DSPF, etc...) file in an RPG program's F-Specs then select Source->Show Fields from the Menu Bar.
  • The above tips only work if the file is externally described in the F specification.

ref PabloMotte, 27 November 2007 (CST)

When you are in RS LPEX, right-click and select Source>Hex Edit line, you will then see the hex value in the iSeries codepage, along with the client codepage.

Also, you can put the cursor on the square, press ESC (to move to the command line) and type "query hex". The "set hex 84" command will set the current cursor position to hex 84 (which turns on 'underline' for the SEU display).

  • Examples of hex codes you can use with "set hex"
    • 80 Normal
    • 81 Inverse
    • 82 White
    • 83 Inverse White
    • 84 Underline

Run a program on your PC

original post [38]

There are several programs that come with System i Access for Windows that can be interesting to use, but you can run other programs on your PC too. Those programs are wrksplf, wrkmsg, wrkprt and wrkusrj They are found in the System i Access program folder. On my default install, that is C:\Program Files\IBM\Client Access To register one of these programs in WDSC 7.0.0.x, take the following steps:

  • Run (from the menu.)
  • External Tools and then select (again) External Tools.
  • Click on the Program config once to select it.
  • Click on the New Launch Config icon on the far left (the one with the plus sign) at the top of the panel.
    • In the Main tab:
      • In the Name box I entered the name of the .exe (e.g. Wrksplf)
      • In 'Location' click 'browse file system' and drill to the exe in the IBM Client access folder and select the exe.
      • In 'Working Directory', copy & paste the path and strip off the final slash and the name of the .exe
    • In the Common tab:
      • In the middle, Display in favorites menu, select 'External Tools' and the new application will show up under Run->External tools
    • Click apply, then run to test. Close the app.

When you select Run->External Tools again it should appear at the top of the context menu. You can change the order they appear on the Run->External Tools context menu by using Run->External Tools->Organize favorites

You can find the list here: [40]

How do you work through learning the functionality of this application?

original post [41]

  • Currently I'm just stumbling through the basics, and I know I'm not doing many things the most productive way.
  • I recommend that you try the tutorials included in the product as well as the PDM/SEU transition to RSE/LPEX - which was revamped and rewritten for v7.0.
  • Also, if you go to the WDSC web site [42] and search the support section - you will find additional tutorials and the labs from COMMON.
  • Don Nitke has a site with a bunch of tutorials at [43]
  • Joe Pluta adds:

You can use the help and tutorials from within the product itself. There are some free tutorials out on the web, including my own first one. You can buy my book, WDSC: Step by Step, which is based on version 5.1.2, but still pretty valid. You can buy my training course from Rochester Initiative which is now available for version 7.

  • You can go to a jumpstart at a technical conference, or an all-day standalone seminar sponsored by your local user group.
  • Or you can contract with someone to come onsite and provide training.
