Incrementing An Alpha Value In CL

[Robert Munday <rwmunday@xxxxxxxxxxxxx>]

Today's task is to increment an alpha value in a CL (A to B to C...).  As some batch files process, I am to save the successfully processed file members to an archive file and assign a batch ID character on the end of each unique member name.  I have a file identifer + Julian Date + AlphaSeq, which for today would be `FL07215A`.  If I process a second batch today, it woud be `FL07215B`.  I can capture the highest value of the eighth character in the file member name with RTVMBRD - RtvMbrD  File(FILENAME) Mbr(*Last) RtnMbr(&LASTMEMBER) as the member names would be in ascending order.  I could then bump the character to the next value and append it to the first seven characters of the member name.

Sure, I could write an RPG program to do this, but there must be a relatively painless way to do it within a CL.  Were it my project, a numeric sequence would be the most simple to accomplish.

How to proceed?

Thanks,
