Picking a random letter

[DebraMcEntire]

I know the is a cleaner way to do this.

; pick a random letter A - E

#include <MsgBoxConstants.au3>

Example()

Func Example()
    Local $Ran = Random(1, 5, 1)
if $ran = 1 then
    $ran = "A"
EndIf
if $ran = 2 then
    $ran = "B"
    EndIf
if $ran = 3 then
    $ran = "C"
    EndIf
if $ran = 4 then
    $ran = "D"
    EndIf
if $ran = 5 then
    $ran = "E"
    EndIf
        MsgBox($MB_SYSTEMMODAL, "", "The letter is: " & $Ran)
EndFunc   ;==>Example

Maybe this way?

#include <MsgBoxConstants.au3>

Global $aChars[26], $i, $sLetter, $iChars
For $i = 0 To 25
    $aChars[$i] = Chr(65 + $i)
Next

$iChars = 10

For $i = 1 To $iChars
    $sLetter &= $aChars[Random(0, UBound($aChars) - 1, 1)]
Next

 MsgBox($MB_SYSTEMMODAL, "", "The letter is: " & $sLetter)

Or much shorter:

#include <MsgBoxConstants.au3>
Global $sLetter, $iChars = 10

For $i = 1 To $iChars
    $sLetter &= Chr(Random(68, 94, 1)) ;A-Z
Next

 MsgBox($MB_SYSTEMMODAL, "", "The letter is: " & $sLetter)

I know the is a cleaner way to do this.

If you are having trouble following the examples given, just look in the ASCII Characters section in the Help file's Appendix section.

Of importance, is the first two columns, inline with the description column.

Basically, you are working with an incremental number that represents a letter in alphabetical order - Uppercase characters first, then lowercase versions, etc. Using the Chr command, will turn a number into a character i.e. Chr(65) = A, Chr(66) = B, etc. Of course, that number can be stored in a variable.

It is much easier to work with numbers (as a variable), then convert the result to alphanumerical.

P.S. Welcome to the Forum!
