bs (Update Breakpoint Command)

The bs command changes the command executed when the specified breakpoint is encountered.

Syntax

bs ID ["CommandString"] 

Parameters

ID

Specifies the ID number of the breakpoint.

CommandString

Specifies the new list of commands to be executed every time that the breakpoint is encountered. You must enclose the CommandString parameter in quotation marks. Use semicolons to separate multiple commands.

Debugger commands in CommandString can include parameters. You can use standard C-control characters (such as \n and \"). Semicolons that are contained in second-level quotation marks (\") are interpreted as part of the embedded quoted string.

The CommandString commands are executed only if the breakpoint is reached while the application is executing in response to a g (Go) command. The commands are not executed if you are stepping through the code or tracing past this point.

Any command that resumes program execution after a breakpoint (such as g or t) ends the execution of the command list.

Environment

Comments

If the CommandString is not specified, any commands already set on the breakpoint are removed.
