ENABLE ATTRIBUTES

DATAFILE Attribute

You can use the DATAFILE attribute to identify the data base file

that a box represents. The syntax of the DATAFILE attribute is:

-----------------------------------------------------------------

| |

| DATAFILE <data-file-name> |

| |

| <data-file-name> |

| |

| is the name of the file that the box represents and must |

| have the following form: |

| |

| [\<system>.][$<volume>.][<subvolume>.]<file-name> |

| |

| \<system> is the name of the system where the file |

| resides. |

| |

| $<volume> is the name of the volume where the file |

| resides. |

| |

| <subvolume> is the name of the subvolume where the |

| file resides. |

| |

| <file-name> is a valid Tandem disc file name. |

| |

| If you omit <system>, <volume>, or <subvolume>, ENABLE |

| uses the CMDSYS and CMDVOL default values displayed when |

| you enter the operating command ENV. |

| |

| This name must conform to the Tandem file name |

| conventions described in Section 5 under the heading |

| "File Name Expansion." |

| |

| The starting value of the DATAFILE attribute is null. |

| ENABLE supplies a default value for this attribute |

| based on the value of the RECORD attribute. ENABLE |

| checks the current dictionary for a description of the |

| record, and uses the file named in that description as a |

| default value for DATAFILE. If the record description |

| names no file, ENABLE uses the record name as the default |

| value. |
