Windows95 - SET/CLEAR REPORT WINDOWS TO DOS PROGRAMS FLAG

AX = 1231h
DL = function
00h set byte after "IsWIN386" to 01h
01h set "IsWIN386" bit 1
02h clear "IsWIN386" bit 1
else
Return:
CF set
AX = 0001h

Return:
CF clear
AX = 0000h

Note: This function is not supported by DR-DOS 7.03 or earlier, by S/DOS 1.0, or by PTS-DOS 6.51

BUG: Windows98 will crash the system if DL>02h on entry due to an off-by-1 conditional jump; if the jump were correct, the function would return CF set/AX=0001h as for Windows95

See Also: AX=1230h - AX=1200h
