PROGRAM File_copy(prd, prr);
{ prd AND prr must match command line file specifiers
with "prr" and "prd" in their path names, either as
suffixes (.prr, .prd), prefixes, or entire names. If
you plan to copy long files with this program, or you
do not want to view the copied file as it is copied,
put comment markers around the `WRITE(current);' and
`WRITELN;' statements. }
VAR current : char;

RESET(prd); REWRITE(prr);
WHILE NOT EOF(prd) DO

END; {eoln loop}
