Parameter Description

letterrange letter, or letter-letter: A letter is one of A to Z. When letter-letter is used, the first letter must be alphabetically before the second letter. Variable names that begin with a letter in this range default to declared type.

DefInt A,C-W,Y' integer

DefBool B ' boolean

DefStr X ' string

' all others are variant

Sub Main
  B = 1 ' B is an boolean
  Debug.Print B ' True
  X = "A" ' X is a string
  Debug.Print X '"A"
  Z = 1 ' Z is a variant (anything)
  Debug.Print Z ' 1
  Z = "Z"
  Debug.Print Z '"Z"
