There are a set of 10 files and a customer will be
selecting random no of files(i.e they may be more than 2,
may not be in the order).Sometimes he might just select
one file or sometimes no files at all.How do you code a JCL
for this? Is it possible to code just JCL alone for this
problem?

Hi,
I don't know the exact answer to this query.
But I have following approach.
Suppose I have a cobol pgm (say) PGM123 that is picking up
files randomly. (We definately need 1 application pgm to
process any of those 10 files randomly. This is my basic
assumption)
I will code a PARM or SYSIN DD * where in my customer can
change order of selection of files .
Say if customer enters PARM as ABCD in order then I will
move this PARM ABCD in a working storage variable in COBOL
PGM and will read each byte A (assign to process file-1)
if second byte is B then process file-2 of third byte is C
then process file-3 and so on. If the cutomer changes this
parm as EDA then files processed will be file-5 then file-4
then file-1.
If any body has different approach pls let me know.
