Hello and welcome to the forum,
list class parameters in jcl
Participaton here requires more than just typing a few words. . . You need to actually explain what you are looking for (why sometimes helps help you also). If you want people here to reply, it is best to post your request as a question rather than a directive. . .
Everything you probably want is here (JCL Language Reference):http://publibz.boulder.ibm.com/cgi-bin/ ... 0/CONTENTS
This is the Table of Contents. The flashlight/tubelight at the top of the page is the "search" feature for the manual.
If you find something that is not clear, post what you found and your doubt. Someone will be able to clarify.
Suggest you bookmark that manual as you should use it often.
It is also not clear if this is a new question or somehow applies to the topic replied to. . .
