Hi: I'm a professor in the engineering department at the local community college and I'm looking for a freeware or shareware DOS program that is a simple calculator with the following attributes: 1. Compact, self-contained DOS program 2. Easy to learn, use and read 3. Does basic math functions 4. Is a stand alone, non-TSR program. The program should fit onto a student's BOOT FLOPPY which contains essential DOS commands and utilities, so size is very important. Less than 32K would be great. The only example DOS program I can think of was the old SIDEKICK calculator. Now I wish I hadn't given it away. I've l looked on the Ziff-Davis shareware site without luck. Thanks, in advance, for your help. Regards, John Chin
