(Subsystem 103)
--------------------------------------------------------------
---------------------------------------------------------------
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.
