FILES Statement Details
 
Syntax
  FILES [filespec]
 
The filespec is a string variable or constant that includes either a
file name or a path name, and an optional device designation.
 
If you omit filespec, the FILES statement lists all the files in the
current directory. You may use the DOS wild card characters--question
marks (?) or asterisks (*). A question mark matches any single
character in the file name or extension. An asterisk matches one or
more characters starting at that position.
 
If you use a filespec without an explicit path, the current
directory is the default.
 
Note that, regardless of the path name contained in filespec,
the header printed by FILES is always the current directory.
