COBOL/400 Language Help
When you specify ALL REFERENCES OF identifier-1, that debugging
section is executed for every statement that explicitly references
identifier-1 at each of the following times:
- Before the execution of a WRITE or REWRITE identifier-1 and
after the execution of any implicit move resulting from the presence of the
FROM phrase.
- Before control is transferred with GO TO DEPENDING ON
identifier-1, and before any debugging section for the
procedure-name runs.
- After each initialization, modification, or evaluation of the contents of
identifier-1 in PERFORM VARYING/AFTER/UNTIL
identifier-1.
- After any other COBOL statement explicitly referring to
identifier-1.
If identifier-1 is specified in a phrase that is not executed or
evaluated, the associated debugging section is not executed.
