PLITEST Subroutine

Purpose

Attaches the PL/I debugger to a set point in a program to be debugged.

Syntax

CALL PLITEST(plitest_commands, plitest_debugger);

Parameters

plitest_commands

A list of one or more commands to set the start location for debugging. Typically, this includes setting the current environment block (ENV <block>;), setting a breakpoint (BR <line#>;), and continuing execution to that breakpoint (C;).

plitest_debugger

A numeric value representing the type of debugger to be invoked.

0 = Use Command-line CodeWatch.

Description

PLITEST is an API called from User programs that causes a debugger to start, attach to a user program, and execute a series of commands before giving control to the user. A PLITEST call is typically inserted in a user application where debugging is to start at a given point in the execution flow.

You can use PLITEST to debug PL/I programs running under CICS, or use the plitest parameter of the -optexec option to do the same. See Compiler Options and Debugging PL/I Programs Under CICS for more information.

Examples

These examples show usage of PLITEST, assuming use of the -bigendian option when compiling.

Example 1:

DCL Debug_Commands  char(1024) varying 
    init('SHLIB MAINP.dll;ENV MAINP;BR TESTLAB;c');
DCL Display_Address char(100) varying init('');
DCL PLITEST_Flags   fixed bin(31) init(1);
CALL PLITEST(Debug_Commands, PLITEST_FLAGS);

Example 2:

call plitest('env MAINP;br START_DEBUG;c', 3);
