I am trying to figure out how to do error checking within a job stream to
see if a file exists before I attempt to stream it.  I have the following in
a job stream:
!IF FINFO('JNBCHECK.JOB.SYS',0)
!  STREAM JNBCHECK.JOB.SYS
!ENDIF
What is happening to me is that Vesoft/Streamx is checking all the stream
statements in my jobstream and when it sees that JNBCHECK does not exist it
give an error that the file does not exist and never streams my job.  If I
bypass the Streamx udc's the job stream works fine.
What can I do to make this work???

*************** We bumped into this same problem today.  Although it has
been a couple of weeks since the original thread, the following solution is
worth sharing.  (Credit to Steve Miller)

!  FILE STRMFILE=JNBCHECK.JOB.SYS
!  RUN STREAMX.PUB.vesoft;PARM=1
!  RESET STRMFILE
!endif
