    Format

      ACCOUNTING  [filespec[,...]]

    filespec[,...]

    Specifies the accounting files you want to process.

    Each file specification can include the percent (%)  and asterisk
    (*)  wildcard characters. If it does not include the device or
    directory, your current default device or directory is used.
    If it does not include the file name or file type, the values
    ACCOUNTNG and DAT are used respectively.

    If you do not specify a file, the command processes the file
    SYS$MANAGER:ACCOUNTNG.DAT.
