8.1.15.4 DEBUGGING Declarative

 



   Debugging sections are permitted only in the outermost program; they are
   not valid in nested programs.  Debugging sections are never triggered by
   procedures contained in nested programs.

X Debugging sections are not permitted in:
The WITH DEBUGGING MODE clause of the SOURCE compiler statement activates all debugging sections and lines that have been compiled into the object program. See Appendix C, "Source Language Debugging" in topic APPENDIX1.3, for additional details.
When the debugging mode is suppressed by not specifying that option of the SOURCE compiler, any USE FOR DEBUGGING declarative procedures and all debugging lines are inhibited.
Automatic execution of a debugging section is not caused by a statement appearing in a debugging section.

USE FOR DEBUGGING
All debugging statements must be written together in a section immediately after the DECLARATIVES header.
Except for the USE FOR DEBUGGING sentence itself, within the debugging procedure there must be no reference to any non-declarative procedures.
procedure-name-1
Must not be defined in a debugging session.
Table 53 shows, for each valid option, the points during program execution when the USE FOR DEBUGGING procedures are executed.
Any given procedure-name can appear in only one USE FOR DEBUGGING sentence, and only once in that sentence. All procedures must appear in the outermost program.
ALL PROCEDURES
Procedure-name-1 must not be specified in any USE FOR DEBUGGING sentences. The ALL PROCEDURES phrase can be specified only once in a program. Only the procedures contained in the outermost program will trigger execution of the debugging section.
