pBreakHandler

Handle user breaks.

Syntax

pBreakHandler ( inout vlStatus )

Parameters

vlStatus

Both an input and output parameter.

Comments

The pBreakHandler function provides a specific method of dealing with user break conditions (for example, Ctrl+Break or Ctrl+C). It would normally be called within an ON BREAK construct.

If vlStatus is BREAK, it assumes that a break has occurred already. pBreakHandler does nothing in this case. Otherwise, the user is informed that a break has occurred and asked if they really want to break. If they select OK, vlStatus is set to "BREAK". If not, vlStatus is unchanged.
