ISFILE Function

Purpose | Determine whether or not a file exists.
Syntax | FileExists& = ISFILE(FileName)
Remarks | The file subsystem is checked to determine whether the file specified by FileName currently exists. If it is found in any form (hidden, system, read-only, etc.), the value true (-1) is returned. Otherwise, the value false (0) is returned. Filename is an unambiguous file name, which may not contain an asterisk (*) or query (?). If it contains one or more of those characters, the function always returns false (0).
