Command_Parameter

 

file-spec

   Specifies the message source file to be compiled. If you do not
   specify a file type, the default is .MSG. Wildcard characters are
   allowed in file specifications.

   If you specify more than one message source file, separated
   by either commas or plus signs, the files are concatenated and
   compiled as a single file.

   If you specify SYS$INPUT, the message source files must
   immediately follow the MESSAGE command in the input stream, and
   both the object module name, identified by the /OBJECT qualifier,
   and the listing file name, identified by the /LIST qualifier,
   must be stated explicitly.
