langfnt
Description
Used internally by PTC ALD in the sluk.3ad or slukwin.3ad files to specify the bitmap fonts used by PTC ALD for its icons, screen fonts and special characters. These bitmap fonts may be different on systems set up for use with other languages.
Syntax
langfnt font name:s slot:n actual size:n range lo:n range hi:n
font name
The name of the bitmap font file to be used: generated via the bmf3b2.exe utility from an ASCII text file containing representations of each 'character'.
slot
The type of item for which the bitmap font is used:
0
Icons
1
Characters 0..127
2
Characters 128..255
3
Extension
actual size
The actual size at which the font has been designed and at which it be optimally displayed. Typically, this is the same as the numerical part of the usual font name, e.g. sxiso_12.3ad will have an actual size of 12.
range lo
The minimum height the edit bar/menu/dialog font, specified using the -h: option when starting PTC ALD (usually with 3b2.bat), should reach before the font name bitmap is used. This effectively matches bitmaps to the screen being used.
* 
The -h option has a default value of 16.
range hi
The maximum -h limit for use of font name.
