I am a beginner on JCL, I am already studying for a while, but still confuse it?

EQUALS =>
What's the function in here? Is same with OPTION EQUALS

If I have two input ps files and they are total approximately 1 million records, And the output maybe 0.5 million records, in this case, what number should I enter after FILSZ, and is it necessary ?

Although it is widespread enough to believe that it is being taught, Control Cards, like those for SORT, are not JCL.

JCL is everything in the JCL Reference, and nothing else.

To your question, yes, that EQUALS is the one from OPTION EQUALS. If you used OPTION EQUALS you would not need it there.

On the FILSZ, basically don't code it unless you have to, for sure using DFSORT (tell us if you are using SyncSORT and the topic will be moved again).

When do you need to? When called from a program and SORT is not reading the records itself; where the bulk of the records on a dataset are wildly variant in length from a guessed "average" length - you will see a message for that.
