I had an ex-mainframe developer ask me today if the 400 has an equivalent
of the DUMMY parameter.  My only thought was to use QTEMP, but that may
not solve the problem.

According to the developer, there was a JCL statement that read:

//DDNAME1 DD DUMMY

where DUMMY meant for the system to ignore writes to whatever was
assigned to DUMMY.  

The need is to save DASD during testing without corrupting the original
code.  My suggestion of QTEMP may fall short, because (I suspect) a write
to a QTEMP file, while destroyed at the end of the job/session, still uses
the DASD while the job runs.  The site I am at is a little short on DASD
and knocking on the 90% threshhold.

Is there a way to ignore all writes to a file via a CL command (probably
some type of OVRDBF) ???

important things in life, there would be a shortage of fishing poles!
