{file-spec [/file-qualifier]}...

   Specifies one or more COBOL source programs to be compiled.  If a
   file  specification  does  not  contain a file type, the compiler
   uses the default file type of COB.

   You can specify more  than  one  input  file  but  you  must  use
   separators.   Each  file is compiled separately when you separate
   the file specifications with a comma.  Files  separated  by  plus
   signs are concatenated in a single compilation.

   No wild card characters are allowed in the file specification.
