I get a variable type mismatch at profile$[count] = file$ when trying to run this.

Function Sign_in()

   Local profile$[5]

   dircheck = ReadDir(CurrentDir$())
   count = 1
   Repeat
      file$ = NextFile$(dircheck)
      If Instr(file$,".pro") Then 
         profile$[count] =file$
         count = count + 1
      End If

      If file$ = "" Then Exit
   Forever
End Function

Can BlitzArrays not be Strings, or have I made some other mistake?

First, use brackets.
Second, use

Dim

You can't use Dim inside a function. I'm trying to avoid making this a global array.

You dont have to make it global, just put it at the beginning of the program.
Its automatically able to be used anywhere.

I don't know why, but you must omit the type specifier when you use the Blitz array, i.e.

         profile[count] =file$

Cp: What then is the difference between declaring it as global as opposed to not?

Floyd: I no longer get the error once I remove the $. However, when I try to print the contents of profile[x] I just get a zero instead of a file name. Did I miss something else?

Function Sign_in()

   Local profile[5]

   dircheck = ReadDir(CurrentDir$())
   count = 1
   Repeat
      file$ = NextFile$(dircheck)
      If Instr(file$,".pro") Then 
         profile[count] =file$
         count = count + 1
      End If

      If file$ = "" Then Exit
   Forever

   For x = 1 To count
      Print profile[count]
   Next
End Function

put the dim command at the beginning of the file, with all the global vars.
you dont need to flag it as global, as you can already use it anywhere in the program + if you do use dim GLOBAL ISN'T ALLOWED.At least for me.

I understand what you are saying. I was trying to avoid having a bunch of arrays declared at the top of the program by declaring them locally inside a function. Since profile[x] isn't used anywhere else in the program I wanted to keep it contained in the one function that does use it.

I was under the impression that it was bad practice to have arrays declared at the top of the program if they are not going to be used throughout it. Is this false?

Use the '$' when you declare the array, just not when you reference it later - it works, try it...

poop

Function poop()
Local a$[10]
a[1] = "Hello"

Print a[1]
End Function

Works like a charm Snarkbait. That is the last thing I would have thought of. How does that make any sense?

Thanks for your help everyone.

It does not make sense.... BlitzArrays were kinda hacked in there long after B3d had been released.
