ASMLANGX needs better support for LOUD WTO message redirection

There is a need to be able to capture an redirect the WTO output that is issued in response to the use of the LOUD parameter during ASMLANGX execution. The use of the _BPXK_JOBLOG environmental variable does not work in this case since redirection does not work for WTP (programmer informational) messages like the following:

+ASMXMA001I ASMLANGX V1.R6.00 (generated 2008-03-17 21:35)
+ASMXMA002I Output file: FOOBAR ASMLANGX A1
+ASMXMA016I Input file: FOOBAR SYSADATA *
+ASMXMA003I ... scanning HLASM SYSADATA file
+ASMXMA010I SYSADATA records scanned: 16
+ASMXMA006I Post-processing begins
+ASMXMA014I Records written to output file: 12
+ASMXMA011I ...Symbols in external search list...... 1
+ASMXMA013I ...Total symbols: 1
+ASMXMA015I Operation completed for this compile unit
+ASMXMA017I Operation completed for this extract file

The _BPXK_JOBLOG environmental variable usage documentation states "Messages that would normally go to the JESYSMSG data set are captured, but messages that go to JESMSGLG are not captured."

In our case we're executing ASMLANGX from a REXX exec in a UNIX shell environment and we're doing this from a software product build cycle where we need to capture and convert the SYSADATA data through the use of the ASMLANGX program with the details of the ASMLANGX execution being piped back to a UNIX (Red Hat) "build bubble" host. There are hundreds and sometimes thousands of assemblies involved in the product(s) build cycle. We do NOT wish to see the WTOs from these ASMLANGX LOUD executions and would like to capture the WTOs related to a particular ASMLANGX execution along with the return code from that execution.

We suggest a couple options; 1) If a SYSPRINT sysout file is present then instead of issuing a WTO ROUTECDE=11 for the above messages write the text of the message to the supplied SYSPRINT DDname which can be redirected easily under the z/OS UNIX shells without the use of the _BPXK_JOBLOG environmental variable, 2) provide for a new parameter in the ASMLANGX parameter string which directs the program to write LOUD messages to that particular DDname.
