** In the IBM mode, the line spacing increment for the ESC 3 n command is controlled by
the Set Vertical Unit commands described below.
This command lets you control vertical movement in fine increments, which helps with the
precise placement of graphics.
In the IBM emulations, the increment of the line spacing set by this command is controlled by
the Set Vertical Unit commands described below.
The actual amount of movement is set by the value of parameter n which can vary, depending
on the emulation:
Table 63: IBM/Epson ESC 3 Command —
Values of Parameter n
Emulation Values of n
IBM PPR 1 to 255
Epson, IBM AGM 0 to 255
Whenever a value of zero is assigned to n, the line spacing command will be ignored.
