Obfuscation? What obfuscation?
Since one MUST either use, short-circuit, or disable The Cycle in any
RPG program, anybody who has any business programming in RPG is going to
be aware of it (otherwise, his or her programs, if they compile at all,
are going to go into endless loops). Therefore, the first three things
anybody should look for in an unfamiliar RPG source member are:
1. Is there a primary file? If so, then the program is implicitly "do
this for every record in the file."
2. Where (if anywhere) is LR being explicitly set on, and under what
circumstances?
3. Where (if anywhere) is there an explicit return, and under what
circumstances?
