Regarding a question about how to check and see if a file exists:

There are two methods. The first is to try and open the file with
Pascal run-time I/O error halting turned off. This is set by the
$I switch; thus, if you include {$I-} in your file, an attempt
to open the file will not halt the program. To see whether the file
was opened successfully, use the IORESULT function.

The second method is to use the FINDFIRST command.

You can find all these functions and options documented in your
manual.
