Alarms that may occur during background editing do not affect
foreground operation. Conversely, alarms that may occur during
foreground operation do not affect background editing. In background
editing, if an attempt is made to edit a program selected for foreground
operation, a BP/S alarm (No. 140) is raised. On the other hand, if an
attempt is made to select a program subjected to background editing
during foreground operation (by means of subprogram calling or program
number search operation using an external signal), a P/S alarm (Nos. 059,
078) is raised in foreground operation. As with foreground program
editing, P/S alarms occur in background editing. However, to distinguish
these alarms from foreground alarms, BP/S is displayed in the data input
line on the background editing screen.
