Swapping array elements

[JRace]

Code: (Select All)

a$ = "12345"
swapLetters a$, 3, 5
Print a$
swapLetters a$, 1, 4
Print a$

Sub swapLetters (a$, n, m)
    t$ = Mid$(a$, n, 1)
    Mid$(a$, n, 1) = Mid$(a$, m, 1)
    Mid$(a$, m, 1) = t$
End Sub

You might want to swap to ASC over MID$, due to the speed and performance difference between the two commands.  Letter swapping is usually something which ends up getting called inside loops, and it could really make a difference in how quickly the overall program performs here.

"ASC" might make a good keyword of the day, "my gosh how it's grown" or "not if you went to Dartmouth" or something like that.

It's definitely my keyword of the day.  I'm gonna drag my ASC back to the Wiki.
