So are you saying the error occurred in process() and you want the line that failed in process()? Wouldn't you instead want a *PSSR subroutine for this? Or perhaps wrap a monitor around the logic inside process()?

Subject: PSDS and Monitor
I've run into a little hitch when attempting to use the program status data structure in conjuction with a monitor block.
Here's the skeleton of a standard mainline for me:
iRC = 0;
monitor;
iRC = process();
on-error;
iRC = 999;
PSDSInfo =
' (' + %char(PSDS_Status) + ')@' + PSDS_Line;
endmon;
if iRC <> 0;
dump(a);
ExceptionInfo =
'** Internal error ' + %char(iRC) + PSDSInfo;
dsply (ExceptionInfo);
endif;
*inlr = *on;
Pretty straightforward. Set error code to zero. Execute process() which returns zero or an error. On error, set iRC to 999 and get the status and failing line from the program status data structure. After the monitor block, check the return code. If it's non-zero, display the error.
The problem? By the time I hit the on-error block, the line number for the PSDS is the call to process, not the line that actually failed.
Let's assume this is a normal program with H specs and a prototype and so on. In that case, the line iRC = process() would be, say, line 18.
So every time I get an error, the line number would be 18.00.
So evidently any entry in the call stack causes the PSDS to be changed.
Is there a way to identify the actual failing line?
