Var Names

[gamerman2360]

Var names can be anything. As long as it does not start with the @ symbol.. Why?

MsgBox(0, "Test", Assign("@", "")); returns 0
MsgBox(0, "Test", Assign("@test", "")); returns 0
MsgBox(0, "Test", Assign("te@st", "")); returns 1

I think thats the only naming limitation. There is no built in length limit.

What do Macros start with? @ComSpec etc....

Might want to re-check that.

Edit:

I should have stated.

Vars must be any of the following characters:

a-z

A-Z

0-9

Vars can be null(Edit: ment to say "any character, even null", also I know this isn't what the help file states but it can be done.), but of course it has to be defined in Assign().

Are var names and macros evaluated in the same way? Would Eval("@ScriptName") return the script name or $@ScriptName?

...

Nope

Tests so far:

MsgBox(0, "Test", Assign("@", "")); returns 0
MsgBox(0, "Test", Assign("@test", "")); returns 0
MsgBox(0, "Test", Assign("te@st", "")); returns 1
MsgBox(0, "Test", Eval("@ScriptName")); returns ""

$msg = ""
For $i = 0 To 255
    If Not Assign(Chr($i), $i, 2) Then $msg &= $i
Next
MsgBox(0, "Test", $msg); Returns 64

Assign(Chr($i), $i, 2) sets the vars to $i because it would hit the var used in the for loop $i and reset it :\. Edited October 31, 2006 by gamerman2360
