- 9
- MESSAGE
**** Escape executed outside of TRY block; CODE = ! (UNWIND 9).
- CAUSE
A Pascal "ESCAPE" statement executed but no TRY/RECOVER block was active anywhere in the runtime stack.
- ACTION
Put a TRY/RECOVER block around the statement which causes the escape, or remove the "ESCAPE" statement from your code (if possible).
- 10
- MESSAGE
**** Non-unwindable descriptor during Escape; CODE = ! (UNWIND 10).
- CAUSE
The procedure assembled with NO_UNWIND in .callinfo statement, or there was an internal error.
- ACTION
Reassemble the procedure without NO_UNWIND, or remove the cause of stack UNWIND (Escape trap).
- 11
- MESSAGE
**** Missing UNWIND descriptor during Escape; CODE = ! (UNWIND 11).
- CAUSE
The procedure assembled with "-U" option, or there was an internal error.
- ACTION
Reassemble the procedure without "-U" option or remove cause of stack UNWIND (Escape trap).
- 19
- MESSAGE
**** End-of-stack during non-local GOTO (UNWIND 19).
- CAUSE
Internal error.
- ACTION
Call your Hewlett-Packard Representative.
- 20
- MESSAGE
**** Non-unwindable descriptor found during non-local GOTO (UNWIND 20).
- CAUSE
The procedure assembled with NO_UNWIND in .callinfo statement, or there was an internal error.
- ACTION
Reassemble the procedure with NO_UNWIND, or remove cause of stack UNWIND (non-local GOTO trap).
- 21
- MESSAGE
**** Missing UNWIND descriptor during non-local GOTO (UNWIND 21).
- CAUSE
The procedure assembled with '-U' option, or there was as internal error.
- ACTION
Reassemble the procedure without '-U' option, or remove cause of stack UNWIND (non-local GOTO trap).
- 30
- MESSAGE
**** No HEAP allocated to release (UNWIND 30).
- CAUSE
Internal error.
- ACTION
Call your Hewlett-Packard Representative.
- 31
- MESSAGE
**** HEAP allocation request FAILED. (UNWIND 31).
- CAUSE
This is a language construct problem. There is not enough contiguous HEAP space available, or there was an invalid HEAP request due to an unitialized variable, bad string length, etc.
- ACTION
Ensure correctness and/or efficiency of the code.
