KBX
Command
Jeff Prosise 1987/No. 16(Lab Notes)
Purpose: Allows entering extended-ASCII line-drawing, foreign language,
math, and science symbols from within word processing programs and editors
that would not otherwise support them.
Format: [d:][path]KBX
Remarks: KBX is a memory-resident utility and is normally
loaded as one of the command lines in your AUTOEXEC.BAT file. At any point
after loading, pressing Alt-Space pops up a window that displays the normal
PC keyboard layout. While this window is on-screen, pressing NumLock shows
the key locations for one of the two extended-ASCII sets; pressing ScrollLock
similarly displays the other extended-ASCII set. Esc closes the display and
returns to any active applications program.
To enter the extended-ASCII characters, hold down the NumLock (or
ScrollLock) key and press the key at the approriate position. Note that the
single-line (NumLock) and double-line (ScrollLock) box-drawing characters are
arranged around the outside of the numeric keypad.
Using the NumLock and ScrollLock keys as additional "shift" keys
avoids conflicts with applications programs that normally use Alt-key and
Ctrl-key combinations. The normal Ctrl-NumLock (pause) and Ctrl-ScrollLock
(break) combinations continue to work without change. When KBX is loaded,
however, Shift-NumLock and Shift-ScrollLock are used to toggle the NumLock
and ScrollLock states.
KBX is not compatible with word processors that normally make use of
the 8th ("high") bit for their own purposes (e.g., WordStar) or that utilize
their own keyboard handlers (e.g., XyWrite). Only experimentation will show
whether the program will work with a given editor.
Note: Since different printers vary in the characters they output when
presented with extended-ASCII codes, you must determine either from your
manual or by experiment whether your printer's character set is compatible
with that PC.
