Hi,


If I remember correctly , MPE/ix opens the stdlist and stdin for every
process and
will not allow  user codes ( unless PM) to fclose the streams directly.

Otherwise a user process will be able to close stdin or stdlist while read
or
write is in progress ( I may not be right on every word!).


In two of the crashes we have experienced , the system dump shows operating
system code in "nl.pub.sys" was attempting to fclose the stdlist and the
file
pointer was not correct. the program that was running was perl5.perl.perl.

I'll will post more as information becomes available.
