Here's a problem that has been bugging me for a whole day now.
What is wrong with this statement?

fprintf( logfile, (isascii(*cp) && isprint(*cp)) ? "[%c]" : [%02x]", *cp);

The problem I'm having is the result of isprint() doesn't seem to be
working.  *cp is defined as an unsigned char *.  This is using MPW3.2b3
(from the ETO CD-ROM).  If I split the isascii() and isprint() out into
seperate lines, assigning their result to two temporary variables, then
logical and the two results in the fprintf line, then everything is
fine.  Naturally, I'm not crazy about having two variables just to deal
with this.
The purpose of this line is to print printable characters as ascii, but
print unprintable ones as hex.
BTW, The statement works in Think C.

Thanks
