Re: COBOL parser

[Ben Elliston]

Hi Alex,

   can somebody tell why COBOL parser is including surrounding quotes in
   the function names?

Because your program identifiers have quotes in the source:

          PROGRAM-ID. "calling_procedure".

Why have you put quotes around the program-id?  I'm not very familiar with
COBOL at all, but every COBOL program I've ever seen have not included
quotes.

Hi,
can somebody tell why COBOL parser is including surrounding quotes in the
function names?

"Symbol Browser" shows the following error when I'm selecting
"calling_procedure" or "called_procedure"
from the list of functions by clicking on the function icon.

==========================================================

list element in quotes followed by "(fu)" instead of space
    while executing
"lindex [$tree get $idx] 0"
    (proc "Retriever&@@expand_classes" body line 35)
    invoked from within
"expand_classes .multisymbr-1.symbr 10 24 display_contents"
    invoked from within
"Retriever& @@ expand_classes .multisymbr-1.symbr 10 24 display_contents"
    invoked from within
"Retriever& @@ expand_classes $this $x $y display_contents"
    (object ".multisymbr-1.symbr" method "Retr&@@handle_click" body line 2)
    invoked from within
".multisymbr-1.symbr handle_click 10 24"
    (command bound to event)

========================================================

Cross reference tool also shows error and refuses to recognize that
"called_procedure"
is refered by "calling_procedure"

There are examples of the procedures, each should be in a separate file:
========================================================
calling_procedure.cbl:

       IDENTIFICATION DIVISION.
       PROGRAM-ID. "calling_procedure".
       ENVIRONMENT DIVISION.
       DATA DIVISION.
       WORKING-STORAGE SECTION.
       LINKAGE SECTION.
       PROCEDURE DIVISION.
       A-MAIN SECTION.
       A-00.
        CALL  "called_procedure".
       A-EXIT.
           EXIT.


========================================================
called_procedure.cbl

       IDENTIFICATION DIVISION.
       PROGRAM-ID. "called_procedure".
       ENVIRONMENT DIVISION.
       DATA DIVISION.
       WORKING-STORAGE SECTION.
       LINKAGE SECTION.
       PROCEDURE DIVISION.

           PERFORM  Z-FINISH.

           EXIT.

       B-INIT SECTION.
       B-00.
       B-EXIT.
           EXIT.
       Z-FINISH SECTION.
