Unfortunately I need to be able to set the values to something arbitrary at
runtime. I don't know at compile time what parts of the help need to be, so
I'm afraid I can't simple use a small set of predefined resource strings.

I wasn't sure that it would (self modifying code... eeuugghh... etc).
Anyway, having gone back to it and played with it a bit, I have managed to
get it to work.
So, for anyone interested in how to do this... here's some sample code:
{
//declare and init vars
Handle resH = NULL;
CharPtr strP = NULL;
//get resource string and lock
resH = DmGet1Resource ('tSTR', 1000);
strP = MemHandleLock(resH);
//!!!
//change value
DmStrCopy(strP, 0, "SNAFU");
//unlock and free
MemHandleUnlock(resH);
DmReleaseResource(resH);
}
Where the '//!!!' is, I obviously need to do some handle resizing... But,
as long as your new string is smaller than the old one, you can use this
code to test the basic principle.
