So to Michael Baker do I speak these words:

I've been thinking along those lines too... Conversion wouldn't really be
neccisary. Give C routines the string starting at the second character, and
pascal routines get the string starting from the first. (size byte) Then
all you have to do is call a routine which recalculates the length byte, or
replaces the nul depending on wether it was altered by a C or Pascal
routine. Then all you've got to do is remember to hand C routines a string
starting at the second character instead of the first. That's where the fun
starts! :-)
