| Title: An Undocumented Switch which will allow you to Expand the |
| Size of the Default Environment Space for DOS 3.0 and 3.1 |

| |
| There is an undocumented switch which may be used in both PC and MS DOS |
| version 3.x which will expand the default size of the environment. This |
| switch may be specified in your CONFIG.SYS using the following format: |
| |
|SHELL = [d:][\path]\COMMAND.COM [d:][\path] /p/e:## |
| |
| Where: |
| |
|[d:]is the drive where the command processor is |
|located on. If the command processor is located |
|on the boot drive, this field may be omitted. |
| |
|[\path] is the path to the subdirectory which contains |
|the command processor.If the command processor |
|is located on the root directory, this field may |
|be omitted. |
| |
| |
|COMMAND.COMis the name of the command processor. This is |
|the name of the command processor found in both |
|PC and MS DOS version 3.x . |
| |
|/pis a required switch to make sure that the new |
|COMMAND.COM with the expanded environment remains |
|resident in memory after DOS initialization. If |
|this switch is omitted then DOS will discard the |
|command processor after initialization, and leave |
|you hanging somewhere in the twilight zone. |
| |
|/e:is the undocummented switch which may be used to |
|expand the size of the default environment. |
| |
|##is a decimal integer between 11 and 63. This number |
|represents the number of paragraphs to be allocated |
|for the environment. A paragraph is 16 bytes of |
|storage. |
| |
| |
| Once again, this feature is undocumented, and it is only available on PC |
| and MS DOS versions 3.0 and 3.1 . This feature may not be available on |
| future versions of DOS. So don't go crying to Microsoft if it does not |
| appear on the next DOS release. |
| |
| |
| Please, let me know if you encounter any problems. |
