1) When you trying to stick some text with $N like $1's, if text contain number, mirc cut the text :
//tokenize 32 Ga is Ga | echo -a $1_some_text /// $1_some1text
2) There is another strange thing :
//Echo -a $mid(text,1,2)Ga
This will echo "te" but i think it should return $mid(text,1,2)Ga since the $mid shouln't be evaluate and here :
//echo -a Ga$mid(text,1,2)
the $mid isn't evaluate.
