var %token = word
echo -ag $remtok(%mytext,%token,32)

var %mytoks = House Tree Bear Ship
var %mytoks = $remtok(%mytoks,Tree,32)
echo -ag Ours tokens are now: %mytoks

The above example shows how you can remove a token from a varible. Echoes Ours tokens are now: House Bear Ship

var %mytext = lol some people lol too often in lol sentences, lol
