EXPANDING THE DOS ENVIRONMENT
The DOS environment is an area in memory where DOS keeps track of
various information, including prompts, path statements, and the
COMSPEC (COMSPEC tells DOS where to find Command.com when it needs
to be re-loaded into memory). This space can also be used to store
user-defined variables using the SET command.
The default environment size is as follows:
DOS 3.1 & 3.2 - 128 bytes
DOS 3.3 - 168 bytes
To Increase the size, add the following line to your CONFIG.SYS
file:
SHELL=d:\path\COMMAND.COM /E:size /P
Where:
d:\path\COMMAND.COM is the location & name of the command
interpreter
/P ensures that COMMAND.COM stays loaded
/E:size is the size of the environment
The size is equal to:
DOS 3.1 - The number of bytes you want divided by 16 and rounded
up.
DOS 3.2 & UP - The number of bytes you want, 32K maximum.
For example, the following line in your CONFIG.SYS file for DOS
3.3:
SHELL=C:\COMMAND.COM /E:1024 /P
Would expand the environment from the default of 168 bytes to 1024
bytes.
