Swapping array elements

[SMcNeill]

You're not swapping any sort of variables...

a$ = "ABCDEFG"
swap mid$(a$,3,1),mid$(a$,5,1)

Evaluate those mid$ functions down:

SWAP "C", "E"

You're not swapping any variable values like that! 


I think what you're looking for is something more like:

Code: (Select All)

a$ = "ABCDEFG"

Print SwapString(a$, 3, 5)

Function SwapString$ (s_passed$, pos1, pos2)
    s$ = s_passed$ 'so we don't change by parameter
    temp = Asc(s$, pos1)
    Asc(s$, pos1) = Asc(s$, pos2)
    Asc(s$, pos2) = temp
    SwapString$ = s$
End Function
