has always (?) had some difficulties with determining the end of file.  If
TP sees an eof ($1a) in the text input stream, EOF becomes true.

  As for speed and freedom from the text file restriction, try blockread and
blockwrite.  End of file on a blockread comes about when you attempt to
read "n" blocks and you only read "i" blocks (i<n).  Read the manual.  You
will need to use all four parameters for the blockread.  If you set the block
size to one (RESET(file,1)), you can determine the size of the file to the
character.  To make these routines fast, make the block size as large as
possible under the 64K byte data segment restriction.
