Taking LD$= for example
Explanation
1.
These instructions compare the strings in S
2.
S and S can contain strings up to 256 characters(16#00 the end symbol is included).

3.
Take the instruction LD$= for example. When the comparison result is that the value in S
continuity condition of the instruction is met. When the comparison result is that the value in S
in S , the discontinuity condition of the instruction is met.
