I don't know anything about DEC machines, but I figure you can trap for the error that occurs when you try to access the file. ie: if the user enters a filename, and you go to get the file and get an error, the user has obviously entered a filename that does not exist. This should work....(I hope =) Chris Krohn Mindlink - Vancouver, BC

What I need to know is how to check if a filename input by the user exists. I have the following types and variables:- type string40 = array[1..40] of char; var in_file_name : string40; data_file : file of char; This is pascal on a Ultrix DEC station, not TP or any other fancy versions. After I prompt the user for the in_file_name and read it in, how do I check to see if the in_file_name given really exists? I need this because if the user enters an invalid in_file_name, the program bombs when I try to access it, which makes sense of course. Any ideas greatly accepted.
