7–65Digital Emulation
Page Format Select (PFS) (continued)
The page home line is the active line after a form feed (FF). The index
(IND), next line (NL), and carriage return characters cause a form feed when
they pass the page end line. Use the vertical position absolute and relative
(VPA and VPR) sequences to move below the page end line. If a line feed
passes the page end line, the printer prints the current page and performs a
form feed to get to the next page.
Ps parameters 0 through 7 are public (ANSI) parameters: ASCII values 0
through 7. The other four Ps parameters are defined by Digital and are called
Digital private parameters. These always start with the ? (3/15) character.
The kind of parameters used affect page format. If you chain commands, do
not mix Digital private parameters with public parameters.
Table 7–13 shows the printable area selected with each PFS format. Text area
is for justified text.
