Getting a Program to Enter Debugging Mode

You can get a program to enter debugging mode (that is, to enter the debugger for

which you compiled the program) at any of these times:

•

Before Execution

•

During execution:

Programmatically

Forcefully

For information on specific debuggers, see Section 15, Debugging Tools.

Before Execution

To have an ordinary HP COBOL program (as opposed to one that is a Pathway server)

enter debugging mode before executing any instructions, start it with the RUND

command instead of the RUN command. Use the same options that you would use

with the RUN command (see Executing an HP COBOL Program).

To have a Pathway server enter debugging mode before executing any instructions,

use the PATHCOM command SET SERVER DEBUG ON. For considerations

regarding errors that can occur when you are debugging a Pathway server, see the

TS/MP Pathsend and Server Programming Manual.

Programmatically

To cause a program to put itself into debugging mode, put this statement at the point in

the program where you want to start debugging:

ENTER "DEBUG"

The process prompts you for debugging commands at its home terminal.

Forcefully

To force an HP COBOL program to enter debugging mode while it is executing, use the

TACL command DEBUG. If you do not have a TACL prompt on your terminal (because

you are not running the HP COBOL program in the background), press Break to get a

TACL prompt. If you include the TERM option in the RUN command with which you

start your program, you can debug the program from a terminal other than the one the

program is running on.
