Example: renaming files with an action (...group, actually).

**Without variables: 453 characters**

> $iflonger($num(%track%,2)$validate([. $replace($meta\_sep(artist, & ), / , & ) - [%title%]],),0,$left($num(%track%,2)$validate([. $replace($meta\_sep(artist, & ), / , & ) - [%title%]],),$sub(248,$len($replace(%\_folderpath%,\Pop,\Pop lossless,\Class,\Class lossless)))),%\_filename%)$iflonger($replace(%\_folderpath%,\Pop,\Pop lossless,\Class,\Class lossless)$num(%track%,2)$validate([. $replace($meta\_sep(artist, & ), / , & ) - [%title%]],),249,…,)

**With variables: 273 characters** (-40%)

> $puts(T,$num(%track%,2)$validate([. $replace($meta\_sep(artist, & ), / , & ) - [%title%]],))$puts(F,$replace(%\_folderpath%,\Pop,\Pop lossless,\Class,\Class lossless))$iflonger($get(T),0,$left($get(T),$sub(248,$len($get(F)))),%\_filename%)$iflonger($get(F)$get(T),249,…,)
