Last time I ... There is a problem, that affects some installations, where Mma calls the wrong shell. The easy way to tell if you have the problem is to do a !ls from the input prompt, and see if the operation succeeds. A universal fix for this problem has not yet been determined, although we have managed to find the cause (and solve the problem) at some sites. There have so far been two cases in which we've been able to duplicate the problem. Case 1: The users environment variable SHELL is not set to a Unix shell. Solution: When practical, modify the math shell script to set this variable to /bin/sh. Case 2: The Apollo does not have the bsd4.3 environment loaded. Solution: Yucky workarounds like loading the bsd4.3 environment, or linking /bsd4.3 to /sys5.3 do work. You can also run the dmps program directly, as Mr. Tonellato does. We should be correcting this problem in the next release of Mathematica for the Apollos. I'm sorry, but I can't give a firm date for the release. Please, please make certain that you have sent in your warranty cards, else we might not be able to send you updates. ----------------------------------------------------------------------- Disclaimer: I am not a spokesman for WRI.
