EVFU/IGP Execute Form Mode

To use the EVFU with the IGP, the EVFU must be loaded while the IGP is in the Execute Form mode. Therefore, you must create and execute an empty form with the IGP prior to using the EVFU load routine. The typical procedure to load the EVFU while the IGP is in the Execute Form mode is as follows.

1.Create an empty form using the IGP Special Function Control Character (SFCC) and Create command. Do not create any form elements and do not use the forms length parameter.

2.End the Create Form mode with the End command.

3.Execute the form using the IGP Special Function Control Character (SFCC) and Execute command. Do not use the form count or page parameters.

4.Enter the EVFU Start Load code.

5.Enter the EVFU channel assignments.

6.Enter the EVFU End Load code.

NOTE: Refer to the appropriate IGP manual for forms creation and execution information.

Relative Line Slewing

Another method for moving paper when using the PI line is to vertically slew a specified number of lines within the form (rather than slewing to a specific line). To do this, three criteria must be met:

PI line must be high

Data bit 5 must be 1 (set)

The EVFU must be the selected Vertical Format Unit

If these criteria are met, a specific number of lines will be slewed based on the status of data bit 1–4 as shown in Figure 6–2 . With bit 5 set and the PI line high, this type of vertical paper motion will occur whether the EVFU memory is loaded or not.
