hi & sorry again !
i don't know how to get around this problem !!
i still can't get the table to work properly !

the table puts the first value into strttmr regardless of the switch
settings

**how do i get the switch settings value to access the corresponding
value
in the lookup table & place it into strttmr? ***

eg     switch setting = 1 0  (rb0 = 1 , rb1 = 0 )
table value at 10 = d'75'
put d'75' into strttmr
the problem area is in the section 'select switch setup '
