Hello
I am reading existing code and Linkage section looks like:

01 LS-PARM.
05 LS-PARM-LENGTH PIC S9(04) BINARY.
05 LS-PARM-DATA PIC X(100).

01 LS-LOG-FILE-NAME-LENGTH PIC S9(04) BINARY.
01 LS-RECORD-LENGTH PIC S9(04) BINARY.
01 LS-RECORD PIC X(27990).

So can I have two parms, not redefined or what is it?

Is it a "main module"?

Are there any SET statements in the program, using ADDRESS OF?

What does the PROCEDURE DIVISION USING have?
