VBScript Function Name Maximum Length

Question

I'm wondering what the maximum allowed length of a function name in Classic ASP (VBScript) is.

Answer 1

The following fails with identifier too long @ 256 characters

for i = 1 to 1024
    execute "function " & string (i, "X") & ": end function"
    WScript.echo i
next

Answer 2

I think it is 255, but you should not abuse it :)

From the MSDN reference for Function:

name
Name of the Function; follows standard variable naming conventions.

And from the MSDN reference for Variables:

[...] A variable name:

• Must begin with an alphabetic character.
• Cannot contain an embedded period.
• Must not exceed 255 characters.
• Must be unique in the scope in which it is declared.
