Blank CDB for Your Application

Copy this worksheet as needed.

Write your own entries in this blank worksheet to suit your application.

Important: Because we cannot predict the number of bit, numeric, or ASCII

entries in your application, we give you a blank word column and extra rows

for each type of entry. Enter the number(s) of the file word(s) for each entry,

and use blank rows as needed. Enter data, ID, and addresses in the formats

that you specified in MCC word 1, bits 8-10. See notes [1] and [2] below.
