NM and CM callable.
Arms a call to the system debugger from a process abort.
Operation Notes |
 |
If the process aborts, Debug is called with a command string that
results in a full stack trace of the CM and NM data stacks and a dump
of the NM registers. This output is sent to the standard list device.
If the process that aborts is being run from a job, the process
terminates after the stack trace and register dump are performed.
If the process is being run from a session, after the stack
trace and register dump have completed, Debug stops
to accept interactive commands with I/O performed at the user
terminal, provided the following conditions are met:
The abort did not occur while in system code.
The process entered the abort code through a native mode interrupt
(typically caused by arithmetic and code-related traps).
When Debug accepts interactive input, the user is free to enter
any Debug command. The user may choose to resume the process or
have it terminate.
If the abort is from a stack overflow, the command list is
ignored, and a stack trace is sent to the standard list
device, and the process terminates. No interactive
debugging is allowed.
The HPSETDUMP intrinsic is a more flexible version
of this intrinsic.
