After mapping these keys and executing the code, you can press any of those
mapped keys and the quoted text will result, followed by the character at the end
of the line (13p, 32p, etc).
Using ANSI.SYS
ANSI.SYS defines functions that change display graphics, control cursor moveĆ
ment, and reassign keys. The ANSI.SYS device driver supports ANSI terminal
emulation of escape sequences to control sequence of ASCII characters, the first
two of which are the escape character (1Bh) and the left bracket character (5Bh).
The character, or characters, that follow these two preliminary characters, speciĆ
fy an alphanumeric code that controls a keyboard or display function.
When you redefine keys, using ANSI.SYS, place the echo on" before the
prompt" statements, so all escape sequences are echoed to the screen; therefore
executing the redefinitions through ASNI.SYS functions. There are other
switches allowed with ANSI.SYS. See DOS help on ANSI.SYS for information.
"
NOTE:
ANSI.SYS distinguishes upper- and lowercase letters. For example “P” and “p” are different.

Remaps extended keys independently on PCĆcompatible keyboards.
Memory Overview (PEN*KEY 6000 Series Computer)
The following paragraphs describe the operation of Windows for the PEN*KEY
6000 Series HandĆHeld Computers and examines some noteworthy design asĆ
pects, to help you understand the concept. Some of these topics include:
"
A little background information about memory.
"
A highĆlevel view of memory, as it applies to the PEN*KEY 6000 Series
computers compared to a standard desktop PC:
"
The typical memory organization of a standard PC, including a pictoĆ
rial view of memory, and how each area of memory is used.
"
A summary of the different types of memory.
"
A list of the commands and statements used in the CONFIG.SYS file
and the AUTOEXEC.BAT file, and descriptions of their usage.
"
Descriptions of Windows, Storage Devices and Memory, as it relates to
the PEN*KEY 6000 Series HandĆHeld Computers.
"
How the PEN*KEY 6000 Series system works.
"
Standard mode vs. Enhanced mode.
"
RAM drive integrityĆprotection.
"
Some nonĆWindows Systems.
Background
When a typical PC is first turned on, it performs a cold boot. Many pieces of softĆ
ware are loaded into the PC's executable memory, or RAM, during the coldĆboot.
The first thing that loads is the BIOS. On a notebook or desktop PC, the BIOS is
usually stored in a ROM chip on the main CPU board (motherboard). After the
BIOS is loaded, DOS is loaded into the random access memory (RAM). In a maĆ
chine that is set up to run in a Windows environment, Windows is the next item
loaded. Finally, an application is selected to run, which is loaded into the RAM.
