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.

Yeah without ASC what's Pete going to joke about?

Actually, when Rob started work on what got officially got labeled as _KEYHIT, he was batting around the idea and posted a proposal to name it _HITKEY. That came to an abrupt end when I replied... "Is there and "S" Pat? Besides, it sounded way too Russian.

And now, back to the future!

I still almost always start use of _keyhit by writing it as _hitkey, before correcting it ! Now I think I'll pay more attention!
