Using the COBOL-IT Debugger

>cobcdb [options] [program name] [command-line parameters]

Command-line parameters

Commmand-line parameters are parameters which would be returned to the program through an ACCEPT from COMMAND-LINE statement.

Program name

Program name is the name of the shared object file created by the COBOL-IT Compiler (.dll, .so).

Options

Options are parameters that are passed to the COBOL-IT Debugger. These options include:

-listdid

Causes the COBOL-IT Debugger to list all the running processes by PID, as well as debug-id.

As an example:

       C:\COBOL\COBOLIT>cobcdb -listdid
       did: -------- pid: 11412 module:
       did: -------- pid: 11956 module:
       did: 12345 pid: 11536 module: hello
       did: -------- pid: 3296 module:
       did: -------- pid: 3324 module:

-n

(Windows only). Causes the COBOL-IT Debugger to start the execution of program name in a new cmd.exe window.

-p <did>

Causes the COBOL-IT Debugger to connect to the running process identified by did (the debug-id). did may be a debug-id, set with the runtime environment variable COB_DEBUG_ID, or it may be the process id (pid) of the currently running process.

When using the -p did parameter, there is no need to specify program name, as the program is identified by did.

-r host:port

Connects two TCP sockets to host:port. The Debugger commands, and the results returned are transmitted via these sockets. This is used by the Remote System Explorer in the COBOL-IT Developer Studio.

Sockets are identified by the first line sent.

Socket1 is used to exchange Command/Result information. As an example, the COBOL-IT Debugger will READ Commands Socket1, and WRITE the results of the command to that socket.

Socket1 is identified by command:pid\n where pid is the process-ID. Socket2 is used to write Debugger Events. For more information see Debugger Events. Socket2 is identified by event:pid\n where pid is the process-ID.

-trace

Causes the COBOL-IT Debugger to write tracing information to cobcdb.out.

-w <did>

Causes the COBOL-IT Debugger to interrupt the process identified by did and set it into a “wait for connect” state. did is the debug-id. Did may be a debug-id, set with the runtime environment variable COB_DEBUG_ID, or it may be the process id (pid) of the currently running process. A program that has been set into this state can be debugged with the –p did command. When using the -w did parameter, there is no need to specify program name, as the program is identified by did.

-y tty

(UNIX/Linux only). Causes the COBOL-IT Debugger to assign stdout/stdin/stderr to tty. When running the COBOL-IT Debugger with –y tty, a program name is required.
