Hi,
Can a WTX map read a mainframe dataset ? I passed the dataset name in the format (and it's variations) as expected in a fopen call. But, it did not work. Can somebody please help me ?

The WTX map (on USS) is being invoked by a DTX node in a WMB message flow with a RUN command. This command has the -IF1 set to override the file name. I hard-coded the IF1 value to a MVS dataset.

With "//'MY.MVS.DATASET'" as the override value, the pair of " were stripped leading to //'MY.MVS.DATASET' which caused an error. I would imagine the reason would be that, the leading // was pointing to the Unix file system.

With further variations and escapes of / and " in "//'MY.MVS.DATASET'" too, there was no result. It seems that, the passed IF1 is being searched w.r.t. Unix file system itself and not in MVS.

I tried the dtxcmdsv command too with -IF1 override. This failed with a CEE3501S abend as :

CEE3501S The module cscr_jpn.so was not found. The traceback information could not be determined. IDI0001I Fault Analyzer V9R1M0 (XXXXXXX 2009/12/16) invoked by IDIXDCAP using SY S1.IFA.PARMLIB(IDICNF00) IDI0034I Fault analysis skipped due to: Parmlib config member EXCLUDE option spe cification Ý1¨ + Done(137) ./dtxcmdsv /my/path/to/compiled.mmc -IF1

I tried with a named pipe too...it did not work.

I created a pipe and then copied the mainframe dataset (with cp) to the named pipe. This pipe was provided as the source file name in the WTX map. The map reads the pipe, says it has zero bytes and terminates.
