I'm currently experimenting with string manipulation in blitz. I was wondering, let's say that I have a string with a number in front of it (eg: 3say, 4must). I can parse out the number using left$(), but how do I change the string to a value? Thanks!

A$ = "3say"
B% = Int(A$)

heh! I thought int was only for numbers! but anyone, thanks so much, gfk!

You don't actually need the Int() - B% = A$ will work just the same. However, using Int() will keep your code more readable.

Perhaps you could clarify this issue:
If you run this code, the result is 35.
what should I to do get it to be 8?

a$="003"
b$="005"

a=Int(a$)
b=Int(b$)

c=a+b
Print c
WaitKey()
End

Use different variables to convert from string to int. A and B have already been defined as strings when you declared them with a$="003" and b$="005". Change the code to c=Int(a$) and d=Int(b$) and e=c+d and it works fine.

Aaah!

I knew it would be an easy fix! :)
The simplest things can be soooo hard to find!

Thanks!
