cDEC$ IDENT string

  Lets you specify a string that can be used to identify an object
  module.  The compiler places the string in the identification field
  of an object module when it generates the module for each source
  program unit.

  The "string" is a character constant containing up to 31 printable
  characters.

  Only the first IDENT directive is effective -- the compiler ignores
  any additional IDENT directives in a program unit.

  IDENT has no effect when you specify the /NOOBJECT compiler option.
