32 Line Matrix Printer Code V Programmer's Reference Manual

Electronic Vertical Format Unit (EVFU)

The EVFU is loaded with a program of line identification codes,

one code for each line of the form. The program includes a Start

Load code to initiate the load routine, a series of line identification

codes, and an End Load code. After the memory is loaded, a line

identification code occurring in the data stream causes the EVFU

to slew to the identified line. To clear the EVFU memory, send a

Start Load code with no channel codes or End Load code.

The Start Load, End Load, and Channel Code commands are

listed in Table 7. A sample EVFU form is shown in Table 8.
