Out of environment space

This issue can be resolved by increasing the amount of environment space by adding the below line into the config.sys file.

SHELL=X:\PATH\COMMAND.COM /P /E:NNNN

X:\PATH\ is the path to where the command.com is located on the computer.
/E:NNNN can be any number from 512 to 1024. It is recommended that you only utilize 512; this is because the more environment space used, the less amount of conventional memory will be available.

Alternatively, as mentioned above, you can do any of the below recommendations to increase the amount of environment space.

• Decrease the path statement.
• If special prompt is defined, remove or slim down the prompt statement.
• Remove any lines from the autoexec.bat and config.sys that may not be needed. This includes switches after commands that may not be needed.
