EVFU Example

EVFU Example

The following EVFU example is a 2-inch form at 6 lpi line spacing. Thus, 12 lines on the form must be defined. The form is repeated 3 times. Paper instructions are disabled.

Assign Line Identification Codes

Line ID Code	Description	Assigned Hex Code
Start Load	Start EVFU	1E
Line 1	Top of Form	10
Line 2	Filler	11
Line 3	Filler	11
Line 4	Filler	11
Line 5	Vertical Tab	1B
Line 6	First channel stop	13
Line 7	Filler	11
Line 8	Filler	11
Line 9	Second channel stop	12
Line 10	Filler	11
Line 11	Third channel stop	15
Line 12	Filler	11
Stop Load	End EVFU	1F

EVFU Format in Execute Mode

The Execute command shown on the next page, derived from the Execute command format on page 59, illustrates how the EVFU data above is incorporated into the Execute command. All other Execute command parameters are shown in italics. (Optional parameters are shown in brackets [ ].) Figure 58 on page 291 illustrates the printed output from this data.

The boldface line below the EXECUTE command represents the hexadecimal EVFU load sequence which identifies the channel codes at which overlay data will be placed on each form. The example hex values correspond to the line identification codes listed above. Channel codes not described above as Filler channels are assigned unique hex codes. Calls to these channels will print overlay data at specific positions on the form.

The two ~AF lines, also shown in italics, represent the dynamic data. While the EVFU does not affect dynamic data positioning (data placement is defined by the ALPHA statement when the form was created), the commands are shown to specify where they would occur in relation to the EXECUTE command, the EVFU load sequence, and the overlay data.
