identify existence of an ascii file in a directory

Dennis,
 
See the "exists" function in fp.  It seems like it will give you exactly
what you're looking for.
 
Regards,

Subject: identify existence of an ascii file in a directory


I would like to do the following:
 
I want to add a header to an ascii file using the export command. I have
no problem doing it on the creation of the file but this file will be
exported to daily until it gets to a certain size, at which time it will
be removed.
 
As an export statement can easily append to the file once it is in
existence, I want to know if the file is there each time I start to
export. If not processing will then create the header (which is a one
time event in the life of this file). Once created then I can export to
the file without having to initiate sending the header.
 
Question: How can I determine that the file does or does not exist.
Important point: This should not be visual as the processing has to be
able to tell if its there and do its job. It must be automated and part
of the processing.
 
Can anyone help me or put me in the right direction. I am on 4.8.
 
Thanks!
