Help! (Context: VAX/VMS, DOE-Macsyma (referred to as Macsyma below.)) I'm trying to make an application which uses Macsyma transparently to the user. I want to be able to communicate between Macsyma and another process. My first attempt was to try to spawn Macsyma as a subprocess with its input and output tied to mailboxes in the spawner. This code works fine with other codes I have that do their I/O on SYS$INPUT and SYS$OUTPUT. However, with Macsyma it doesn't work. Macsyma seems to be using the terminal directly. (When the spawn is given the Macsyma banner etc. just comes up on the terminal instead of being written to the mailbox.) Does anyone know or have any ideas on how I can get an environment set up to do what I want? Thanks, ---------- Joe P. Garbarini Jr. Lawrence Livermore National Lab P. O.
