Hmm. My problem is this: Here's example from DDE, but aplies to
any/all plugins that allow callbacks.
Suppose dde wants to callback with a string that contains
newlines. dde doesn;t know the name of a variable, all it knows is
some script to invoke, with the result string as an argument. I tell
user to provide callback definition in this form
?$.scriptname("#")$
and I'll stick the result in the place where I encounter the insertion
point, namely #.
But if I put an actual newline in beetween quotes, and send command
back to PowerPro, pp sees two lines, not one.
So, if I can substitute \n \r (and \x00 while I'm at it) I can sneak
the string in as a callback arg.
But for that I need the esc char.
Other suggestions?

Nice, but I was hoping for something simpler. Maybe Bruce can gimme
another ppsv func.
