Another quick question, how would I use an array with Select?

Local MyArray:string[5]

Select MyArray
Case
EndSelect

How would Case work? :o

select is just a different way of doing an "if then elseif"

this :

if a = 1 then 
  ------
elseif a = 2 then
 -------
elseif a = 3 then
 --------
elseif a = 4 then
 --------
else
 --------
endif

is the same as this:

select a
     case 1
      ------
     case 2
     -------
    case 3
     -------
    case 4
     -------
   default
    --------
end select

so it depends what you want to do with the array that will determine how you construct the select/case.

if you explain exactly what you want to do, there might be a way or an alternative route for you to take.

How about this...

Local myarray1:String[] = [ "a", "b", "c", "d" ]
Local myarray2:String[] = [ "a", "b", "c", "d", "e" ]

CaseArray( myArray1 )
CaseArray( myArray2 )

Function CaseArray( array:String[] )
	Local a$
	For Local b$ = EachIn array
		a$ :+ b$
	Next 
	Select a$
	Case "abcd"
		Print "myarray1"
	Case "abcde"
		Print "myarray2"
	End Select 
End Function

I guess you could do this:

Local myarray1:String[] = [ "a", "b", "c", "d" ]

Select True
	case myarray1[0] = "a" and myArray1[1] = "b"
		print "yes"
	default
		print "no"
End Select

But it's fugly.

Concatenate all your strings together and then check...a bit like a 'key field' in some databases.
