USE DEBUGGING

USE DEBUGGING traces procedure-names as a program executes. Immediately

before a procedure is executed, the code for the section containing USE DEBUGGING

is executed. If you collect and report procedure-names from a special register as the

program executes, you can monitor the actual sequence of operations and detect logic

errors.

The symbolic debuggers are significantly more versatile than the USE DEBUGGING

statement. For information on the symbolic debuggers, see Run-Time Debuggers.

ALL REFERENCES OF name

is checked for syntactic correctness but diagnosed as unsupported. If the selected

debugger is symbolic, use the BREAK command to observe all uses of and

changes to a data item.

file-name

is checked for syntactic correctness but diagnosed as unsupported. If the selected

debugger is symbolic, use the BREAK command to observe all uses of a file.

procedure

is one or more procedure-names to trace during program execution. procedure

cannot be named in multiple USE statements.

Note. The 1985 COBOL standard classifies USE DEBUGGING as obsolete, so you are

advised not to use it, even in TNS HP COBOL programs. The NMCOBOL compiler does not

recognize it.
