Program Example:
1. When X0=ON, the data stack D10~D19 is compared against D0 and the result is stored in
D50~D54. If there are no equal values, the contents of D50~D52 will be 0.
2. The offset into the data file of the largest value of all compared data will be stored in D54 and
the offset into the data file of the smallest value of all compared data will be stored in D53.
When there are more then one largest value and/or smallest value, only the last location in the
data file will be recorded for each. For example, if there were a K5 in D17 and D18 in the table
below, the value stored in D53 will be 8 instead of 7. This is because the last occurance of the
smallest value in this case is in position 8 in the data file.
