Step 1: Getting Attribute Data into Arc/INFO

DEFINE - Issue the DEFINE command with the file name to create a new data file template.  You will be prompted for the attribute name, size, and type of each item in a new data file.

Arc:   tables

enter command:  define landuse.dat

item name:  landuse-id(common name and definitions to match

item width:  4attribute table to which you wish to join)

output width:       5

item type:             B

item name:           lu-code (new variable)

item width:  3

output width:       3

item type:             I

item name: <return> (to end)

If you make a mistake while defining the file, the command ERASE will delete the file, and you can start over.  Or use ALTER or MODIFY.

Look at what you have created with the ITEMS command.
