Open in online IDE ;Substring Function(gets the string located at A,B of string) Function Substring$(s1$,a,b) length = b - a J$ = Mid$(s1$,a,length + 1) Return J$ End Function trigstring$ = "Hello my name is Zach" Print SubString$(trigstring$,3,8) WaitKey() ;This prints "llo my"

I hate to burst your bubble, but "INSTR" is a function that deals with this. But good thinking though... :)

Instr doesn't do this, Instr finds one string in another.

He's right you know, Instr doesn't do this.

but I think mid$ might.

mid$(string$,3,5)

The issue is whether you want "startposition - end position" or "startposition - amount", that function does the first, mid$ does the second..

Exactly.
It's a simple function, but it makes working with strings appear much nicer.
Whenever I do stuff with strings, it ends up looking really confusing and messy because of things like Mid(string$,start,(end-start)+1)

Only nitpick I could mention is the x,y .. typically you'd see those vars for anything 2d'ish, while this thing here reads from a 1d string. I'd avoid x,y and use x1,x2 or a,b or start,end etc.
