DIM question (Was MOVE/MOVEL and %Scan)

[J Michael Smith <JMichael.Smith@xxxxxxxx>]

Barbara,

Could you provide an example of "The parameter DIM, OCCURS and PERRCD
keywords no longer needs to be previous defined."

Thanks

Michael Smith

I don't recall that ever being the case, but my memory may be failing.
Maybe you're recalling a problem with the debugger - it didn't handle
varying fields very well, at first.

Paul, you remember correctly.  This is one of the changes listed in the
"What's new in this release" section of the V5R1 ILE RPG Programmer's
Guide.
Point 4 in Other enhancements: "The search string in a %SCAN operation
can now be longer than string being searched. (The string will not be
found, but this will no longer generate an error condition.)"  It was
your question about this behaviour, maybe on this mailing list, that
prompted the change.
