I don't know if this can be done, but here goes... In the text for an alert, ^0,^1,^2,^3 are treated as special strings to be replaced by ParamText. Believe it or not, I actually want the strings "^0" and so on to appear in my alert, and not to be substituted. Is there any way of escaping them or otherwise when specifying the text in a .r file for Rez, so that they come out literally and are not substituted? Or do I *have* to say something like ParamText("^0","^1","^2","^3"); ?

I have no idea how to do this, except for the fainly absurd, (like making a PICT item that has a picture of your StatText) but I'm pretty sure that even the above won't work. ParamText("^0", "^1","^2","^3") will set up an infinite loop, since that's the way ParamText works. -Sho

You can't do it that way. That will generate an infine recursion, since text ^0 contains text ^0 etc. This was done one purpose so that you could have a paramtext that contains another parameter. You can put a null (ASCII 0) between the two offending characters so that they will not be recognized. I don't know if you can create the nul with Rez, but you can do it with ResEdit by first writing some other character instead of the null and then editing the DITL with the hex/ascii editor. You might also try creating a PICT with the strings in it. _._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._ | Juri Munkki jmunkki@hut.fi jmunkki@fingate.bitnet I Want Ne | | Helsinki University of Technology Computing Centre My Own XT | ~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~

There, now I'll explain why. It is very easy to cause an infinite recursion inside the toolbox by trying to substitute like this. I know, I did it once. The strings you pass in get re-expanded, and then re-parsed to check for any of the special sequences (e.g. "^0".) This is a great feature, but you can have problems with it. I would suggest putting a very narrow blank character between the "^" and the number. Shane Looker | Looker@um.cc.umich.edu America works less, when you say "Union Yes!"

There is a simple way to get "^0" in a dialog/alert, though admittedly it does burn *two* slots: ParamText('^', '0', '', ''); This does work (I tried it before responding), so in conjunction with some smart Concat's you ought to be able to get the message you want.
