Chapter 8 PGL Graphic Parameters
Vscale Parameter
Due to the difference between horizontal and vertical DPI, as the size of blo ck
characters increase, there is a greater disparity betw een the physical size of
horizontal and vertical output. This parameter allows you to print ver tical block
characters larger than size 3 at approximately the same sc ale as horizontal
block characters.
Examples: Size 10 Characters
Zero Parameter
The Zero Parameter allows you to set all zeros to print as slashed zeros (Ø).
This makes it easier to distinguish zeros from th e upper-case letter O. The
default for the Zero Parameter is Slashed.
SFCC Parameter
This parameter gives you another method of changing th e Special Function
Control Character. The default is the ASCII tilde (~, HEX 7E, Decimal 126)
character.
