Hi:
Haven't tried any of this, but
from a quick glance at the code in genSubRecord.c it seems
to me that the output links are always "put",
which explains what you see.
The eflg is only checked in monitor() to decide which monitors to send
for the fields VALA, VALB, ...
Try a simple camonitor your_gensub.VALA.
So if you leave your OUTA empty, but make
 someOtherRecord.INP = "your_gensub.VALA CP"
you might only get updates from your_gensub to someOtherRecord
when your_gensub changes value.

I have created a genSub record, myGenSubRecord, for which the
subroutine does nothing.
For myGenSubRecord I set:
OUTA = "someOtherRecord PP"
EFLG = "ON CHANGE"
if I cause myGenSubRecord to process then so does someOtherRecord
which is not what I would expect for this value of EFLG. Am I
misinterpreting the meaning of EFLG?
