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?

Answer / yogendra shinde
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.

Answer / tony prabu
First of all you can not just do this by jCL alone you
definitely need a application program like COBOL to do this.
Then depending upon the selection using sysin we can select
the file usin the EWVALUATE verb etc.

Answer / piyush mani
obsly file will b either in form of ps or pds so we can
accept the input of user dynamically(sysin/parm) as a ws variable
like this
//sysin *
4
1
5
6
7
/*
//
here 4 is the no of record we r selecting and cobol progr will run the logic of file-open para 4 times
and then we can open the file
as per d user requirement...
this is a cobol approach but how 2 do it by using jcl
plz any1 tell me...

Answer / bella
if you giving user an option to select u should create CICS
programs with prim screan for selection of any numbers of
files. Or none (exit)

Answer / shridhar
Depending on option it is easy. relate every entry in cics
to a no or alphabet. This use as evaluate in cobol.
as per options create a JCL in cobol an submit it to intrdr
for further process.
Your option on CICS screen and file names relating to those
options should/will be matching.

Answer / ajay tyagi
Question is not so easy. first of all we need to understand
customer requirement. actually what does he want to do with
files?
once we have clear view then we can suggest some solution
