I'm having a senior moment!  What is the simplest method of determining
in a Basic (RiscOs 4.02) program whether a named file exists in a
particular directory?

e.g. A file called test might/might not exist in my <Data$Dir>
directory. If it exists then I wish to remove it but don't want to
create an error if it doesn't exist!

Regards to all,
