Theft is the highest praise for someone else's work ;)
True words :) Thanks! — feel free to use it in whatever way you like.
BTW, under these new circumstances I should mention there is a little peculiarity. That is, you need a trailing space at the end of the text (noticed the space in "laborum. ) def"? - that's there on purpose). The space itself will not be visible, but without it, the last line might not wrap properly in some cases. (I've always wanted to fix this bug, but then again, making sure there is that space has always been easier... ;)
As to Forth, yes I've tried it and generally liked it. Though, due to largely missing library functionality in the environment I used at the time, it has always been somewhat tedious to get any real world problem solved with it... That definitely is a plus of PS, its powerful builtin typesetting and graphics facilities.
