GET ROW AND COL FOR A DSPF FIELD FOR CSRLOC

ref: [[8]][[9]]


This is an example program showing the usage of the GETROWCOL procedure.

Its purpose is to set up the ROW and COL for CSRLOC to position to a FIELD in error without the need for indicators.

You can use a ERRMSG or ERRMSGID on a dummy O field so you will still need to use one indicator for an error.

If you use ERRMSG or ERRMSGID you will need to position the cursor with a Write before you turn on the indicators for ERRMSG and ERRMSGID.
