I would like to thank everyone who helped on the file reading and plotting problem. Due to lack of time I cannot answer individually, and will post a summary later also, but i would like to express my thanks.
btw, Soon I will be getting some macros, that so certain operations on the file in the same format. Those macros written by someone else are for Mathcad. I would like to know if there is anything that any of you know that mathcad can do and mathematica cannot? Are there anythings that MathCad can do and Mathematica is clumsy about, and vice versa? Is this group an appropriate place for posting the macros so that I can get help on translation, or is there another group more appropriate?
