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.

Example:

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"
End Sub
