Syntax:  SET LANGUAGE COMPILE COMMAND compile_command
              defined_language

  Specifies the default command string for the COMPILE command.

  This string is the command used to compile a buffer when the COMPILE
  command is used.  If the language has diagnostic capability, and you
  want a diagnostics file created for use with the REVIEW command, you
  must specify the diagnostics switch in the command.  For example, on
  OpenVMS systems:

  SET LANGUAGE COMPILE COMMAND "CC/DIA"
