Hi Jasmin
I am new to this group here is wat u have asked for JCLLIB has mainly two properties:
1) if u dont specify the steplib under exec then jcllib dsn name will be taken as pds where the load module of the program is present
2) if u specify both jcllib and steplib steplib will override jcllib
please let me know if u need clarifications..!!
correct me if am wrong
Thanks
