FILE * intermedf = (FILE *) NULL;
char *interfn = 
#ifdef DOSTMP
 "frtXXXXXX";
#else
 "/tmp/frankasm.XXXXXX";
#endif

It used to be /usr/tmp/fr..., but that didn't work too well with no tmp
directory on the /usr partition 8-)

I'm not sure if the code is correct or not, since it turned the
(pid % 10) into a multiply, but that shouldn't affect the destination
at 0(r5).  and it's not like that address should be there, since
the for loop just above it scaned the whole string...  I compiled
it with "-S -g", and noticed that it put the line markers in at
0x95a1 for line 83 "pid /= 10;" and line 82 starts at 0x9560.  Like
I said before, it's probably something stupid, but it looks real
wierd to me right now.

Thanks again,
Jon
