Hi there!

Cannot create any alias $script* like $scriptmovie.

Step in aliases:

Execute:

Thats is normal?

$script

Returns the filename of the currently executing remote script.

$script(N/filename)

Returns the filename for the Nth loaded script file. If you specify a filename, it returns $null if the file is not loaded.

$script(0) return the number of script files loaded
$script(2) returns the filename of the 2nd loaded script file
$script(moo.txt) returns $null if the file is not loaded, or moo.txt if it is.

Note: This cannot be used to reference the users or variables files.

To be exact, some identifiers (but almost all directories identifiers) accept trailing text, it is very common to see in script something like "$scriptdirtest.txt" where test.txt is appended to the value of $scriptdir, just as though $+ were used.
$scriptmovie is naturally just $script $+ movie for mIRC, so this is a limitation.

Note that mIRC supports two custom identifiers prefixes '.' and '/' which allows you force mIRC to call the custom alias: if you had an override of the 'me' alias, $me would still call the built-in identifier while $.me or $/me will call your custom 'me' alias. These prefix allows to workaround the limitation; $/scriptmovie will call your alias, but it's not so good practice to use that, renaming the alias to something else would be better.
