Ctrl F9 - Set a conditional breakpoint
 Trigger a breakpoint when expression evaluates to .T.
──────────────────────────────────────────────────────────────────────────────

 This option allows you to set an expression against a breakpoint.

 You may enter an expression against a breakpoint. Instead of a breakpoint
 being triggered and program execution being halted, the expression is first
 evaluated. If the expression evaluates to .T., then the program execution
 is halted and the debugger is summoned.
