This article was previously published under Q40705 SUMMARY
In MS-DOS versions 3.30 and 3.30a, the ANSI.SYS driver can be used to
reassign some of the keys on the keyboard to perform a user-defined
function. The entire keyboard cannot be redefined. The number of keys
that can be redefined is limited by a reassignment buffer size
internal to ANSI.SYS. The size of this buffer in MS-DOS versions 3.30
and 3.30a is 200 bytes.
MORE INFORMATION
Public-domain ANSI.SYS substitute drivers are available that provide
a larger buffer to redefine more of the keys.
