>What I really want, is a function which can split text into separate lines. I want pass two parameters, the text and the number of characters per line, and to have the formatted text returned. Every line, except the last one, should end with chr(13)+chr(10). I don't want words to be split, and I don't want signs, like comma, point, exclamation mark and so on to be moved to the beginning of a new lines. Sounds easy, but I have found it to be much trickier that I thought. Or maybe it's just me who have entered weekend mode too early?

Are you assuming monospace font (given that you state each line having a specific number of characters) ? If you can assume monospace font, then setting _MLINE to the number of characters per line and using ALINES() will probably give you something close. On the other hand if you want it to work with proportional fonts, then it will probably a tad more complicated (e.g. "walk" through each "paragraph" [e.g..text separated by newline sequence] word-by-word trying to "fill" line buffer with as much text [using TXTWIDTH() to measure the size] before it exceeds the specified line length).
