Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - Programming Languages
Product - COBOL Compilers
For recording keeping, the previous attributes were:
Brand - Rational
Product family - Design & development
Product - COBOL Compilers
Since COBOL subprograms run fine with no GOBACK STOP RUN or EXIT PROGRAM, and the compiler cannot tell if a program is a MAIN or SUB program, any message would be misleading.
It's right; I get no runtime error if i haven't goback in subprograms. But I need GOBACK or . . within my _main_ program. Therefor this should be flagged (as information not warning) if no goback/exit programm exists.
Allthough cobol standard allows to write programs without goback that isn't good programming. Is it?
Thanx

I tested with a main program and got the runtime error. Have a look on

I've seen now that your answer was was for "sub programs". I wll test a.s.a.p.
>> A program with no GOBACK, EXIT PROGRAM, or STOP RUN is legal and will run correctly as a subprogram, << I'm astonished!
I will check once more and give an answer (with code) as soon as possible.

A program with no GOBACK, EXIT PROGRAM, or STOP RUN is legal and will run correctly as a subprogram, per the COBOL Standard: An implicit EXIT
PROGRAM statement is generated if the called program has no next executable
statement. So, are you asking for a non-standard compiler option to flag such legal programs?
