Appendix A: Programming Worksheets

General

The programming worksheets provide a convenient method of defining your NCR 7870 program before loading it into the unit. Each worksheet relates to a Specific Programming Mode.

Purpose

The programming worksheets permit you to determine the exact sequence of tags to scan for each programming parameter. It also provides you with a hard copy of the program for possible future use.

Format

The top half of each worksheet identifies the programming parameters and the specific tags for each one. Most of the worksheets contain arrows that guide you through the proper sequence. The bottom half of each worksheet provides a place for you to write in each of your selections.

Shortcuts

Most of the worksheets contain shortcuts that permit you to enter specific parameters without entering the entire worksheet. These parameters have an alpha character in a box just left of the parameter name. Scanning the Hex tag that corresponds to the alpha character enables input for that parameter. You then scan the tags that pertain to that parameter. After entering the specified parameter, the program returns to the Base Programming State.
