Re: [open-cobol-list] Bug in GnuCOBOL 1.1: reporting undefined paragraph

[Alan Jump]

Let's try this again, since I managed to misdirect this to just Scott the first try.

Under GnuCOBOL 2.0 (compiled about a month and a half ago on Kubuntu 14.04.1):

$>cobc -x badperform.cob

badperform.cob: In paragraph '2000-do-some-stuff':

badperform.cob: Error: '3000-shut-down' is not defined

badperform.cob: Error: syntax error, unexpected end of file

Compilation failed.

When I PERFORM an undefined paragraph (probably because I mistyped the paragraph name, GnuCOBOL 1.1 reports my blunder, naturally.  However it attributes the error to the last paragraph in the program, not to the paragraph where the error actually occurs.

Consider the following minimal example:

       IDENTIFICATION DIVISION.
       PROGRAM-ID.  badperform.

       PROCEDURE DIVISION.

       0000-mainline.
           perform 1000-begin-job.
           perform 2000-do-stuff.   *> misspelled
           perform 3000-shut-down.
           STOP RUN.

       1000-begin-job.
           display 'I am starting up'.

       2000-do-some-stuff.
           display 'I am doing stuff'.

       3000-shut-down.
           display 'I am shutting down now'.



>cobc -x -Wall badperform.cob
badperform.cob: In paragraph '3000-shut-down':
badperform.cob:8: Error: '2000-do-stuff' undefined


The error should have been attributed to 0000-mainline, not to 3000-shut-down.  If GnuCOBOL can't keep track of where the error occurs, it shouldn't attribute it to any particular location; that's just needlessly misleading.


Environment: Red Hat 4.1.2.  I have not tried GnuCOBOL 2.0; maybe it behaves better in this regard.
