Operands:
S1: Start device of data stack S2: Device to be searched D: Start device for storing search
result (occupies 5 consecutive devices) n: Stack length
Explanations:
98. SER instruction searches for the value stored in S2 from the data stack starting with S1, with a
stack length n. The search results are stored in the 5 registers starting from D
99. D stores the total of the matched results; D+1 stores the No. of device storing the first matched
result; D+2 stores the No. of device storing the last matched result; D+3 stores the No. of
device storing the smallest value; D+4 stores the No. of device storing the biggest value..
100. If operand S2 uses index F, only 16-bit instruction is available
101. If the instruction applied 32-bit instruction, operands S1, S2, D, n will specify 32-bit registers.
102. The range of operand n: n = 1~256 (16-bit instruction), n = 1~128 (32-bit instruction)
Program Example:
103. When X0 = ON, the data stack D10~D19 are compared with D0 and the result is stored in
D50~D54. If there is no matched result, the content of D50~D52 will all be 0.
104. D53 and D54 store the location of the smallest and biggest value. When there are more than
one smallest and biggest values, the devices with bigger No. will be recorded.
