system.debugger.b

Command system.debugger.b Command/System Debugger
Applicable release versions: AP, R83
Category System Debugger (42)
Description establishes a "breakpoint" condition which causes the system to enter the system debugger when the condition is met.

The optional "offset" sets a particular breakpoint within the mode, at the specified "offset". If no "offset" is specified, the debugger "breaks" at every available breakpoint within the mode. In AP, every assembler instruction is an available breakpoint. In R83, only labels are available breakpoints.

The "data.reference.specification" may contain a maximum of two numeric parameters, hence no window specification is expected.

A plus (+) character is displayed for each breakpoint successfully entered into the table, until the table is full. The maximum number of breakpoints at one time is four.
Syntax b{data.reference.specification}{.offset}
