Problems with "Hugs for Windows"

[David Gray]

I have students using Hugs for Windows, Version: December 2001.

Unfortunately, string handling appears to be somewhat erratic.

I have attached one example.

If this program is loaded and the following expression evaluated a number of
times, each evaluation gives a different (usually wrong) result.

dose (p,x) i

Everything works correctly with the command-line version of HUGS.

Thank you for your time.
