HEBREW FOR AMIGA
Hebrew, Arabic, Farsi, Urdu and other laguages are written
from Right to Left (RL languages). It seems that the AMIGA rom
kernel was designed to support this direction of writing.
On page 204 of the Rom Kernel Reference Manual under font prefernces
a variable FPB_REVPATH is specified for this purpose.
The description is insufficient for me, and the example on page 213
is not very informative. I hope that sombody can help me with the
following questions:
1. How can disk font be specified such that it will be rendered
RL. The font editor on the EXTRAS disk does not permit the selection
of the RL option in the 4th menu.
2. If I "setfont" to a font that was designed to be rendered RL,
and then use any existing word processor, will the text that I
type authomatically be rendered RL?
I'll appreciate a C language example demonstrating the use of these
facilities by scanf() and in string gadgets (especially the one
that provides the cursor position to be in the right side of the
gadget).

In the new Amiga ROM Kernel Technical Reference Manual:Libraries and Devices,
this is made a bit clearer. I re-wrote the example program from the old manual
so that it handles reverse-path fonts correctly.
The Font Editor _will_ allow you to select reverse-path from the menu, but
you must first load in an existing font and change its "Font type" to
Proportional. If you don't do the latter, you won't be able to alter each
character's Space entry. For reverse-path fonts, the Space should be small
or negative; the Kern should be a large, negative number (approximately the
width of the character). If all the characters have the same Space value
when you are done, you can set the font type back to fixed-width.
No, not all programs correctly handle reverse-path fonts.

This never worked :-( It will not be supported for 1.4. )No, not all programs correctly handle reverse-path fonts. Very polite :-). *Most* programs do not correctly handle them, including lotso ours :-(. -- Bob Burns, amiga!kodiak _ | /_ _|. _ | Commodore __ |_) _ |_ _ )' |<(_)(_)|(_\|< /\ | ||| _` /\ |_)(_\| )(_\ | | \ Software ___/..\|\/|||__|/..\___ Faith
