4.1.1 SOURCE-COMPUTER Paragraph



The SOURCE-COMPUTER paragraph describes the computer on which the source program is to be compiled.

computer-name
A system-name. For example:


         IBM-390

WITH DEBUGGING MODE
Activates a compile-time switch for debugging lines written in the source program.

A debugging line is a statement that is compiled only when the compile-time switch is activated. Debugging lines allow you, for example, to check the value of a data-name at certain points in a procedure.

To specify a debugging line in your program, code a 'D' in column 7 (indicator area). You can include successive debugging lines, but each must have a 'D' in column 7 and you cannot break character strings across lines.

All your debugging lines must be written so that the program is syntactically correct, whether the debugging lines are compiled or treated as comments.

The presence or absence of the DEBUGGING MODE clause is logically determined after all COPY and REPLACE statements have been processed.

You can code debugging lines in the Environment (after the OBJECT-COMPUTER paragraph), Data, or Procedure Divisions.

If a debugging line contains only spaces in Area A and in Area B, it is treated the same as a blank line.

Except for the WITH DEBUGGING MODE clause, the SOURCE-COMPUTER paragraph is syntax checked, but has no effect on the execution of the program.
