Search a Data Stack
The 16-bit instruction, n = 1~256, S1 occupies n components, D occupies 5 components.
The 32-bit instruction, n = 1~128, S1 occupies (2×n) components, D occupies 10 components
S1 : the head device ID number of a defined data stack
to be searched
S2 : the compare data source at the searching
D : the search result's storage head device ID number
n : the search stack length of the searched data
The data stack is assigned by consecutive devices which headed with . This instruction will compare the
content value at the specified to each device in the data stack, and store the comparison result into 5
consecutive devices headed with .

For a search data stack formed by D0 ~ D9. When X20= “ON”, this instruction uses the D10 to compare with the
stack D0~D9 and store the result into D20 ~ D24. (Assune the content value of parameter D10=100.)

The content value at the +3 and +4 will record the larger data position number when there’s more than
one minimum or maximum value in the data stack.
