Taking FOR= and DFOR= for example
Explanation:
1. The instructions are used to compare the value in S
compared are floating-point numbers. Take the instruction FOR= for example. When the
comparison result is that the value in S
is met. When the comparison result is that the value in S
condition of the instruction is not met.
