WINDOWS
Purpose: Sets the system compatibility level when working with
MS-Windows.
Syntax: WINDOWS <ON|OFF|STANDARD|286|ENHANCED|386> [/V:version]
Where 'version' sets the Windows version number, e.g., 3.0
or 3.1
By default: WINDOWS ON /V:3.0
Note:
MS-WIndows requires additional DOS code and system data located in the
lower areas of the memory, depending on its version and mode
(real/standard/enhanced). To achieve the best results, both mode and version
number should be specified. For example:
WINDOWS STANDARD Assumes that MS-WINDOWS 3.0 is to be used in
WINDOWS STANDARD /V:3.0 standard mode.
STANDARD and 286 are synonyms, just as the ENHANCED and 386.
WINDOWS 286 /V:3.1 MS-Windows 3.1 in standard mode
WINDOWS 386 /V:3.0 MS-Windows 3.0 in enhanced mode
WINDOWS=ON assumes the version is 3.0 with the mode set maximum
according to the type of processor used. For the 286-class machines, it is
STANDARD, while for 386 and up - ENHANCED. It is not recommended to use the
SYSGEN command together with the WINDOWS command, as the system generation
may be incompatible with that required by MS-Windows. WINA20.386 (a driver
supplied with the system) is required for running MS-Windows 3.0 in the
enhanced mode (see the VXD command description).
