REALbasic Tip: Global constants for non-printing characters

[Geoff Perlman <geoff at realsoftware dot com>]

Global constants cannot be assigned non-printing characters such as carriage
return, horizontal tab, etc. The obvious solution is to simply create local
constants where you need them but that's reinventing the wheel every time.
Fortunately, there is a more elegant solution.

In a module, add functions that return the various characters you require.
Here are examples of functions that return carriage return, horizontal tab
and space:

Function CR ( ) as string
  return chr(13) 'carriage return
End Function

Function HT ( ) as string
  return chr(9) 'tab
End Function

Function SP ( ) as string
  return chr(32) 'space
End Function
