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