I've got a problem with the IDEAL picture language. I have written a front-end to ideal which produces simple x-y plots. IDEAL doesn't have a "Draw a point" command, so I just draw a very short line. Now, it would seem to me that the time to process a program which draws 2*n lines should be twice that for processing n lines. But it's not. Ideal takes ~10 minutes on a SUN to crank out 1000 points, ~40 minutes to crank out 2000 points, and I for 5000 points, I left the job running over night and killed it after it had eaten up > 700 minutes! Anyone have any ideas? BTW, the output is going to an Imagen 5/480. Does anyone have a filter for leroy output for this machine? We can get it working in Tektronix mode, but the output is really marginal. Respond by mail. I'll post a summary if there is interest. Thanks. Mark F.

Remember, IDEAL is finding an optimal solution to simultaneous equations. This makes it really slow for large problems. To draw simple pictures via troff, use PIC instead.
