REXX: SIGNAL ON FAILURE isn't working (Not recognized).

[BertramMoshier]

My REXX program template (which I just uploaded) does:

/------------------------
| Enable trap processing |
*------------------------*/
SIGNAL ON ERROR
SIGNAL ON FAILURE
SIGNAL ON HALT
SIGNAL ON NOVALUE
SIGNAL ON SYNTAX

I found REXX on VM/CE isn't supporting SIGNAL ON FAILURE

When REXX hits the statement SIGNAL ON FAILURE the following appears as the error:

template exec
29 - SIGNAL ON FAILURE
Error 25.3 running template, line 29: SIGNAL ON must be followed by one of the keywords ERROR, HALT, NOVALUE, NOTREADY or SYNTAX;
found "FAILURE"
Ready(20025); T=0.16/0.20 11:17:41

SIGNAL ON FAILURE was added to REXX in VM/SP Release 6, after REXX had been available on VM for about 5 years.
It was never implemented in BREXX. This feature will be added to VMCE. FAILURE will be signaled when executing a CMS command (including the CMS CP command) produces a negative return code.

It looks like SIGNAL ON ERROR doesn't work correctly either. It is not being signaled when a CMS command gets a non-zero RC.

========================
/* */
ADDRESS ''

SIGNAL ON ERROR

'ACCESS 333 Z'
EXIT RC

ERROR: SAY 'ERROR SIGNALLED'

Currently returns:
test2
DMSACC113S 'Z (333) ' NOT ATTACHED
Ready(00100); T=0.02/0.02 10:03:18

Should return:
test2
DMSACC113S 'Z (333) ' NOT ATTACHED
6 - 'ACCESS 333 Z'
+++ RC(100) +++
ERROR signalled
Ready(00016); T=0.02/0.02 10:03:05

Down load a test fix from https://www.dropbox.com/s/xrbt2nlcv2958aj/brexxfix.aws?dl=0

This is an aws tape made with a TAPE DUMP BREXX TEXT command.
Retrieve the test aws file, and use TAPE LOAD to create a BREXX TEXT file.
IPL CMS, so that the new BREXX TEXT file will be loaded, then test with a SIGNAL ON FAULRE sequence.

I don't know how Bob Bolch intended to fix this, and his Dropbox link is now dead, but I've written a fix of my own and sent a pull request to the main source tree.

Thank you for the fix. As a Rexx programmer, I appeciate having VMCE Rexx (BRexx) woking properly. Bertram Moshier WB8ERT
