[comp.sys.next] NeXT Mathematica Problems

estes@iris.ucdavis.edu (Robert Estes) (06/10/89)

I've been having problems with Mathematica, op. sys. 0.9.

First, and most importantly, is there any way to stop a Mathematica calculation
once it has started??  I seem too put myself into infinite loops all the time 
and have to logout to stop them.  The suggested keystrokes, Control-C and 
Control-., don't seem to work.

Also, I've been using WriteNow to print my Mathematica Plots.  I just Cut them
from Mathematica and Paste them in WriteNow.  Seems to work OK, but I get 
malformed Postscript errors frequently and not quite as frequently the printer
hangs (Unable to connect to npd.)  Is there a way to free up the printer without
a full reboot??  Also, any reasons for the malformed Postscript errors???

I hope these questions haven't been answered before.

Thanks a lot.....
