[oops...]

What I meant was that reading a big block is a lot faster than reading
char by char using fgetc() and such (getc, getchar).  If you are going
to read a big block you might as well use low level calls (Fread) for
maximum speed.  But I guess you _could_ use fread() as supplied by your
compiler vendor.  Just hope they implemented it efficiently...

One more warning: if you use a compiler with 16-bit int's (as it should be
on a 68000!) you are limited as to the amounts you can specify in the
count arguments for fread(), malloc(), etc.  You _have_ to descend to
the raw OS calls if you need to use a long count.
