String as a command

Consider the following situation: There is a string containing a comand, e.g. "A = B". How can I make BB executing the comand if the string itself is a variable? I hope you understand what I mean...

You could convert this: Evaluate String Arithmetic or use this might work.. Quick Math Evaluator or take a look at BVM

Well, the comand could also be more complicated like "if A then B", everything you could think off. I am interested in a more general solution to this.

Then use BVM.

u could write the string to a file and then use Include

Beaker (Posted 2007) [#6]

That wouldn't work, because you can only include a file at compile time.

Hi, Let me know if I am off base. I understand what you want blitz to do, the problem is that it is a compile then run language. It will not accept a command string you will have to look at an interpreter type language. I am not familiar with bvm, that might do what you want. I had the same idea once upon a time then I created a "Sub Language" to talk to blitz. I used the text commands and made my own parsing code and that allowed me to make my graphics seem to have a mind of there own and access the stuff blitz does using my own strings. The commands I made up were not pretty, but practical. For Example, my command look like "[CS1,1]". This command in particular made a sound play out of slot 1. That is all.
