jeez dude, don't go into to much detail, each character is one byte and they add up you know. i don't think sumo wants to go over his bandwidth because you decided to type up the encylopaedia.
ok, sorry, i just woke up.
what are you talking about? please use details. unless i'm missing something here.

well, you need to learn how to "parse expressions".
Deleter posted a nice recursive descent expression parser a while ago... maybe he will show you when he sees this topic. =)

Basically you need to convert the string into individual numbers: Use MID$() and ASC() to get the ASCII value of each character and then create IF statements that figure out what to do. I agree, Deleter's parser is an awesome example.

red_Marvin's Equator program is my preference (although I've never tried Deleter's).

Freebasic is like QB, except it doesn't suck.

though recursive stuff can be hard for a newbie to learn...
edit: just realized that uses string indexing, which is not supported in qb, if you want me to rewrite it quick so it works for qb then say so.
