Special Routine For Stack Unwind

**** Escape executed outside of TRY block; CODE = ! (UNWIND 9).

A Pascal "ESCAPE" statement executed but no TRY/RECOVER block was active anywhere in the runtime stack.

Put a TRY/RECOVER block around the statement which causes the escape, or remove the "ESCAPE" statement from your code (if possible).''

**** Non-unwindable descriptor during Escape; CODE = ! (UNWIND 10).

The procedure assembled with NO_UNWIND in .callinfo statement, or there was an internal error.

Reassemble the procedure without NO_UNWIND, or remove the cause of stack UNWIND (Escape trap).

**** Missing UNWIND descriptor during Escape; CODE = ! (UNWIND 11).

The procedure assembled with "-U" option, or there was an internal error.

Reassemble the procedure without "-U" option or remove cause of stack UNWIND (Escape trap).

**** End-of-stack during non-local GOTO (UNWIND 19).

Internal error.

Call your Hewlett-Packard Representative.

**** Non-unwindable descriptor found during non-local GOTO (UNWIND 20).

The procedure assembled with NO_UNWIND in .callinfo statement, or there was an internal error.

Reassemble the procedure with NO_UNWIND, or remove cause of stack UNWIND (non-local GOTO trap).

**** Missing UNWIND descriptor during non-local GOTO (UNWIND 21).

The procedure assembled with '-U' option, or there was as internal error.

Reassemble the procedure without '-U' option, or remove cause of stack UNWIND (non-local GOTO trap).

**** No HEAP allocated to release (UNWIND 30).

Internal error.

Call your Hewlett-Packard Representative.

**** HEAP allocation request FAILED. (UNWIND 31).

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.

Ensure correctness and/or efficiency of the code.
