mrp batch in mfgpro without mgbatch

[gregor.weertman]

I want to run the MRP without the batchmode.
I try this.

DEFINE STREAM strm_mrp.
OUTPUT STREAM strm_mrp TO mrp.plog NO-ECHO KEEP-MESSAGES.
INPUT FROM ../MRP.dat.
RUN mf.p NO-ERROR.
INPUT CLOSE.
OUTPUT STREAM strm_mrp CLOSE.


MRP.dat:
"username" "passwd"
"mrmpup.p"
"34601" "34601" "no"
"MRP"
.
.
Y


when I run this I get this message:

Site: 3212 To: 3212

Synchronized Calculation: no
Synchronization Code: Output: xerox_is
Batch ID:
WARNING: OUTPUT DEVICE ENTERED IS NOT A DEFINED PRINTER.
Report is now running. Press control-C to cancel.
** There is no terminal. (120)
End of report.
Process complete.

end it quits.

The MRP did not start. It did anything.
Is there a way to do that?
What does the mgbatch.p do to make the MRP run in batch?
