Creating a Message File

Message files can be created in several ways. To create a message file with the :BUILD command, use the MSG keyword. For example, to build a message file named PAULA, enter:

   :BUILD PAULA; MSG 

When a user process opens a new file programmatically and indicates that it will be a message file, the HPFOPEN intrinsic creates the new message file. Or HPFOPEN can explicitly reference a :FILE command. Use the MSG keyword in the :FILE command to create a new message file:

   :FILE LARS, NEW; MSG 

When you perform a :LISTF,2 command, message files are identified by an M in the third column of the TYP field. For example:

   FILENAME  CODE -----LOGICAL RECORD------ -----SPACE----- 

               SIZE   TYP  EOF   LIMIT  R/B  SECTORS  #X  MX
