Chapter 4 Form Example

Design the Form

1. First, design the form on a grid as shown in Figure 28. A standard grid

example is provided in Appendix C. Designing the form on the grid allows

you to decide where each form element will be placed. Compensate for

expanded alphanumerics and plan for the logo.

Enable Code V Graphics

2. The Code V must be enabled for the Graphics Mode using the Graphics

Mode Enable command (PY). This is the first input to change the Code V

from the Normal Mode to the Graphics Mode.

Format: (cc)PY (cc)-

Enter: ^PY^-

3. To avoid accidentally terminating the graphics command sequence by a

host-generated terminator, enable the Free Format command (F). This

allows the Code V to accept the data as one continuous stream even

though the data may contain host-generated paper motion commands.

When Free Format is enabled, the Code V only recognizes the Free

Format command terminators: Carriage Return (^-), Form Feed (^,), Line

Feed (^*), Vertical Tab (^+), and EVFU commands.

Format: (cc)F (cc)-

Enter: ^F^-

4. To begin form processing at a top-of-form position, send a Free Format

Form Feed command (,).

Format: (cc),

Enter: ^,

5. The Code V is now ready to accept the commands and data for the form.

Most of the form and form elements are designed using the extended

graphics command set. Consequently, one of the alphanumeric

commands or the Interrupt command must be used to introduce, or

enable, the extended graphics commands. Begin by inputting the

Standard Alphanumeric command (M) immediately followed by the Dark

Print command (KF) to produce the form in a darker contrast. No other

Alphanumeric command parameters are needed at this time.

Format: (cc)M(cc)KF

Enter: ^M^KF
