Heck, we can get SBC's of just a few square inches with a Pentium Pro, 128 Mbytes of RAM, SVGA output, and a hard drive interface, why not just install Windows NT on the SBC so you can run the latest and greatest Visual BASIC++++? Well, I took your argument there a little too far, but I hope you get the point: Use the tools appropriate to the job. And for most SBC applications, the floating point capabilities and libraries as well as the file I/O facilities of a "full-up" BASIC are overkill. OTOH most Tiny Basic implementations are perfect for the bit-banging and input/output that a SBC is often called upon to do. (And yes, I know of other cases where Windows NT and 128 Mbytes of RAM on the SBC are appropriate, but I don't think any of us want to go down that road!) -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
