Summary
The following are the RPG/LE fully free-form definitions and instructions needed for using the Strip Formatting service procedure. This service procedure simply allows the caller to strip all specified formatting delimiters out of a character string. If the delimiters are omitted then, by default, only blanks are stripped—including embedded blanks.
Service Prototype
Place the following in a separate copybook for inclusion in both the caller and the service program source members.
**free //============================================================================== // Strip all occurrences of the specified delimiter(s) from a string -- // including embedded occurrences of those delimiters. If delimiters // are omitted, then all blanks are stripped by default. //============================================================================== dcl-pr GenUtl_StripFormatting varchar(512) rtnparm; StringValue varchar(512) const; DelimsValue varchar(64) const options(*omit); end-pr;
Service Procedure
Place the following in a service program source member.
**free
//==============================================================================
// Strip all occurrences of the specified delimiter(s) from a string --
// including embedded occurrences of those delimiters. If delimiters
// are omitted, then all blanks are stripped by default.
//==============================================================================
dcl-proc GenUtl_StripFormatting export;
dcl-pi *n varchar(512) rtnparm;
StringValue varchar(512) const;
DelimsValue varchar(64) const options(*omit);
end-pi;
dcl-s x packed(3:0);
dcl-s OutputString like(StringValue);
if %parms() < %parmnum(DelimsValue); // if omitted strip all blanks by default
OutputString = GenUtl_ScanAndReplace(' ': %trim(StringValue): '');
else;
OutputString = %trimr(StringValue); // else, strip only trailing blanks
for x = 1 to %len(DelimsValue); // loop on formatting characters
OutputString = GenUtl_ScanAndReplace( %subst(DelimsValue: x: 1)
: OutputString: '' );
endfor;
endif;
return OutputString; // return result string to caller
end-proc;
