VAM file

[Michael C. Lee]

We use mailbox files in our system and they are declared as follows:
File CMBX_FILE                                                                &
  Organization DIRECT                                                         &
  open *CMBXFILE                               &
  NOCREATE

  Record CMBX_FILE
&
    Description "    This file is used as a mailbox file for background jobs "
&
                "It is a message flat file of the MPE file system which      "
&
                "remove the record entry once the record has been read.      "

And the file is listed on the HP as follows:

FILENAME  CODE  ------------LOGICAL RECORD-----------  ----SPACE----
                  SIZE  TYP        EOF      LIMIT R/B  SECTORS #X MX

CMBXFILE*          56B  VAM          1       1052   4      272  1  *
