Printer
When you select the
Printer
option from the Setup and Configuration menu,
you get a list of common printers. You can select a printer from this list or you can
select
Create<Ins>
to add a printer if it is not listed. By selecting
Edit<F3>
, you
can modify the parameters for a listed printer or a printer you have added.
Refer to Chapter 7 for information on printing and printer configuration.

sWapping/Expanded memory
When you select the
sWapping/Expanded memory
option from the Setup and
Configuration menu, you get a screen with several memory-related parameters.
These allow you to optimize the use of conventional memory (the first 640K of
RAM memory), expanded memory, and disk space in your personal computer.
During editing or file manipulation, it is common for the conventional memory of
your personal computer to fill completely. When this happens, the BASIC
Development Software may attempt to move portions of a file into expanded
memory or onto a disk drive. This memory swapping is done with no effect on you
as a user.
You should find out how much expanded memory (EMS) your personal computer
has before setting values to any of these parameters. As you become more proficient
in using this software and begin using shell to DOS or user-defined program
features, you should determine the maximum program size that you expect to use
and allocate memory accordingly.
The memory swapping parameters here are similar to those in the compiler setup
screen that you access when setting up a compiler for a specific filename extension
(Chapter 8). Be aware that any memory swapping method selected for a compiler
overrides the method selected here when that compiler is used. Refer to the help
screens for details.
IMPORTANT
The BASIC Development Software uses expanded memory, not
extended memory. Most 80386-based personal computers come
with software (typically called EMM for Expanded Memory
Manager) that allows you to designate some of your memory as
expanded memory. Some 80386 and most 80286, 8088,
8086-based personal computers need a special board for
expanded memory. Refer to the hardware and DOS
documentation provided with your computer.
IMPORTANT
Verify your personal computer’s expanded memory size before
selecting your memory option. If sufficient memory is not
available, a system error may occur.
