Program Flags Using the command * n (n = 0 − 31), the user can store program flags in
the program flow stack of the interrupt stack. These program flags reflect
the program flow prior to program abortion.
The program flags can be set by the user at arbitrary points of the pro
gram. As soon as the program arrives at a flag point, this is stored in the
flow stack. In this way, the user has a rough image of the most recently
executed program.
