Are those 2 different questions?
1) HOW TO USE A PERFORM IN COBOL?
2) USING PERFORM TO EXECUTE MY PASSWORD HOW DO I USE IT?
PERFORM is a COBOL verb that means to go elsewhere in your program and then return back. Much like a BALR & BR 14 in Assembler. Here is a snippet from one of my manuals:
The PERFORM statement is a PROCEDURE DIVISION statement which transfers
control to one or more specified procedures and controls as specified
the number of times the procedures are executed. After execution of
the specified procedures is completed (i.e., for the appropriate number
of times or until some specified condition is met), control is
transferred to the next executable statement following the PERFORM
But to ‘EXECUTE MY PASSWORD’ is unclear what yo mean.
