$replacex
From Scriptwiki
Replaces any occurrence of substring in string with newstring except for replacements that have already been made.
$replacex(string,substring,newstring,...)
This is the same as $replace but it doesn't replace already replaced text (see example below).
$replacexcs is the case-sensitive version of $replaxce.
Example
; set a test text var %mytext = This is moo ; actually replace substrings var %mynewtext = $replacex(%mytext,is,moo,moo,foo) ; echo it to the active window echo -a %mynewtext
This example will echo Thmoo moo foo as at first is was replaced by moo and after that, all moo that are no replacement, replaced by foo.

Take a look at $replacexcs for the case-sensitive version.
Use $replace (or $replacecs) for 'normal' replacing (inclusive already replaced substrings).
