8.17.4 Examples

Example 1:

Add entries to the list of allowable tape automount directories.

HHC00013I Herc command: 'automount add D:/MVS/Tape'

HHC02203I default allowed automount directory: 'D:/MVS/Tape/'

HHC00013I Herc command: 'automount add D:/MVS/Cart'

HHC02203I allowed automount directory: 'D:/MVS/Cart/'

Example 2:

List all currently defined list entries of allowable tape automount directories.

HHC00013I Herc command: 'automount list'

HHC02217I '+D:/MVS/Tape/'

HHC02217I '+D:/MVS/Cart/'

Example 3:

Delete an entry from the list of allowable tape automount directories.

HHC00013I Herc command: 'automount del D:/MVS/Cart'

HHC02220I Entry deleted

8.18 B (Set breakpoint)

8.18.1 Function

The B (or B+) command sets a breakpoint. The argument gives an instruction address or a range of
addresses where you wish to halt the execution. Once the breakpoint is reached, instruction execution is
temporarily halted and the next instruction to be executed is displayed. You may then examine registers
and / or storage etc. To continue execution after reaching a breakpoint, enter the “G” command.

The “B” command is synonymous with the “S+” command.
