Re: [Bug-GnuCOBOL] Abortion on undeclared vars: IF U1 = 1 and U2 = 2 or U1 = 2 and U2 = 1

[Edward Hart]

Hi Harald,

Thanks to Ron and Simon, as of r1755, this bug no longer occurs and we have better error messages:

./test.cob: in paragraph 'main':

./test.cob: 8: error: 'V1' is not defined

./test.cob: 8: error: 'V2' is not defined

./test.cob: 9: error: 'V1' is not defined

./test.cob: 9: error: 'V2' is not defined

./test.cob: 10: error: invalid _expression_

./test.cob: 8: error: invalid _expression_

./test.cob: 10: error: invalid _expression_

./test.cob: 10: error: invalid _expression_

Hi,

 

I’ve found another abortion error in a syntactically wrong program,

originally caused by a missing copy.

Please have a look if a better error msg can be printed.

Hint: Simplifying the relational expressing will solve the abortion

 

       IDENTIFICATION DIVISION.

       PROGRAM-ID.  DK0100.

       DATA DIVISION.

       WORKING-STORAGE SECTION.

      * variables intentionally not declared for provoking the abortion

       PROCEDURE DIVISION.

       main.

           IF  V1 = 1 AND V2 = 2 OR

               V1 = 2 AND V2 = 1

           THEN

               display "Hello"

           END-IF.
