Using the Relate Environment

The relate environment is usable from ARC, TABLES, ARCPLOT and ARCEDIT.  It is not usable from INFO.

Items out of related files can be used in Arc/INFO anywhere that an item name is specified.

A relate does not store the table from which the relate operates; therefore, multiple coverages can be related to the same data file

When using ADD, if a relation name already exists in the current set of relates, it is replaced by the new relate with the same name

The general form for using fields out of related files is:

relation name//INFO item name

If the INFO data file to which we created a relate named SOREL also contains an item called distance, we can create a distance buffer:

Usage:  BUFFER <in_cover> <out_cover> {buffer_item}

Arc:  buffer soils soilbuf sorel//distance
