Summary of Features

The following is a list of CodeWatch features.

Controlling Program Execution

CodeWatch has control over the execution of the program. Program execution can be started at a specified point, stopped and resumed at different points, transferred from one point to another, and terminated at any point.

• Breakpointing: Breakpoints can be set to suspend execution at specified source program statements. The status of the program can then be evaluated or modified.
• Catching: Process control can be returned to the debugger when a given signal is generated.
• Stepping: Program execution can be stepped by one or more source program statements at a time. The debugger can also step into, over, or out of a called procedure.
• Tracing: Tracepoints can be set at statements or at procedure and block entries to track program execution.
• Watchpointing: Watchpoints can be set to monitor given variables. When the contents of a watched variable change, program execution stops and control is returned to the debugger.

Examining the Source Program

CodeWatch allows you to examine the source program, find specified text strings, move to specified line numbers, and examine included source files.

Environment Control

CodeWatch allows you to set the evaluation environment it uses to provide scope for referencing a specific instance of a variable or statement.

Symbolic Access

The value of a variable can be examined and/or altered as program execution continues. Procedure entries and exits can be monitored at the debugger command level. Expressions can be evaluated using the Evaluate command.

Action Lists

One or more of the debugger commands can be combined and executed at step and breakpoints.

Macro Facility

Macros can be defined as a sequence of debugger commands that will be used repeatedly throughout a debugging session. The macros can then be used like any other debugger command.

Command Files

Debugger command files can be created with a text editor or by logging commands to a specified file during a debugging session. These command files can then be used to execute the predefined sequence of debugging commands automatically during a debugging session.

Issuing Error Messages

CodeWatch identifies error conditions and issues meaningful, complete sentence error messages.
