Here is a clear scenario in full details
I have a jcl which is kind of tools. This jcl perform takes 2 input file and gives 2 output file.
Now, my requirements are
1. To first lock this jcl so that no users other than me can see it.
2. Trigger this JCL using a REX program.
What this rex will do or holds ?
THis rex will ask for 2 Input files and 2 output files as shown in below link.
As I have no much idea of REX I have already started another topic here,clist-rexx/topic6906.html
3. These 2 input files names will be replaced by INPUT 1 and INPUT 2 in JCL and same for output.
Finally through Rex, the jcl gets triggered.
