*The character (E or F) is placed in program buffer A at one
position greater than the number of available print lines per
form. For example, if there are 60 print lines per form, the
character (E or F) would be placed in position 61 of program
buffer A.
Figure 54. Vertical Skip Stop Characters
Tab stops are indicated by placing a T in the desired
positions in program buffer A. When a T is encount-
ered in the currently selected printer format buffer,
horizontal tabbing is initiated.
Vertical skip stop positions are indicated by placing skip
stop characters in the desired positions in program buffer
A. Vertical skipping is initiated when an S is encountered
in the currently selected printer format buffer. Each
position in program buffer A represents one line on the
printer form. When the printer prints a line and a carriage
return occurs, a counter increments to the next position
in program buffer A. Therefore, the number of lines that
are skipped when a skip is initiated is the number of posi-
tions from the current position to the indicated vertical
skip stop character.
When both a horizontal tab stop and vertical skip stop
character are required in the same position in program
buffer A, a second set of skip stop characters is used.
Figure 54 shows the vertical skip stop characters that can
be used to combine vertical skip and horizontal tab stop
characters.
The following is an example of vertical skipping. Assume
that a 2S has been encountered in the current printer
format program and the printer is currently on line 5 of
the form. Figure 55 shows how the skipping would occur.
