Page 4-11 CHAPTER 4 — PROGRAMMABLE FUNCTION STRINGS
0E — LINEDEN
This is used to set the line density at the printer. This PFS is sent to the
printer whenever the System changes the line density setting in response to
an SCS Set Line Density or Set Single Line Distance command.
Although the 5250 ALLY normally performs vertical movement at the
printer using PFS 0D — VERMOVE, there are two reasons that the printer
may need to know the actual line density.
1. The user can cause the 5250 ALLY to use Line Feeds (PFS 09 —
LF) instead of PFS 0D — VERMOVE by setting Option 46 —
Vertical Movement to Line Feed (!AGILE!46=02;).
If the 5250 ALLY is using Line Feeds to perform vertical
movement, the printer needs to know the line density so that the line
spacing created by the Line Feeds will be correct.
2. If the printer supports continuous feed paper (i.e., fanfold) then the
printer needs to know the length of the paper so that it can move the
correct distance when it receives a Form Feed. Most printers set
forms length as a number of lines per page after the line density has
been set. (See PFS 0F — PAGELEN below.)
The new line density is sent as the parameter of this PFS and is
converted to the unit of measurement specified by Option 48 —
Vertical Resolution.
0F — PAGELEN
This is used to set the length of the form, and it is sent to the printer in
response to an SCS Set Vertical Format or Set Initial Conditions command.
This is usually needed only for printers that use continuous forms, such as
fanfold paper. Because the length of the form is set in lines per page, the
line density must be set correctly at the printer in order for the forms
length to be set properly. For this reason, PFS 0E — LINEDEN must be
set correctly in order for this PFS to work.
10 — P 5CPI
Print 5 characters per inch in portrait orientation. This PFS is sent to the
printer when the 5250 ALLY’s page orientation algorithm has selected a
portrait orientation, and when the System has requested a font with a pitch
of 5 CPI or less (using either an SCS Set Character Density command or
an SCS Set FID through GFID command).
