'Try this:

'Day of Week - Dick Dennison 10/26/89
'$INCLUDE: ''    'load qb with the /L switch
'Interrupt 21 Function 2AH - get date
DIM InRegs AS RegType, OutRegs AS RegType
DIM Day(7) AS STRING * 3
Day$(0) = "Sun": Day$(1) = "Mon": Day$(2) = "Tue": Day$(3) = "Wed"
Day$(4) = "Thu": Day$(5) = "Fri": Day$(6) = "Sat"
CLS = &H2A * 256   '2Ah in ah
CALL INTERRUPT(&H21, InRegs, OutRegs)
' * * * cx is the year, dh is the month, dl is the date, al is the day
PRINT; " = year"
PRINT OutRegs.dx \ 256; " = month"
PRINT OutRegs.dx MOD 256; " = date"
daynum% = MOD 256
PRINT "Day of the week is "; Day$(daynum%)
