以下是引用东方红一红在2014-11-20 17:14:17的发言 >3楼：JUR OPERAND:简单而言，就是直接跳转到制定语句。详解如下。
Jump relatively
Interrupt linear program scanning and continue at the point
specified by the jump displacement.

Processing the "JUR" Operation
Execution of the "JUR" operation is independent of the RLO.
The parameter specifies the jump displacement directly. For example, parameter "1" means that
processing will continue with the next one-word statement. Parameter "2" means processing will
continue with the one-word statement directly after the next one-word statement.
Such labeling includes the following special features:
? The jump displacement is not corrected automatically. If changes are made in the Section of
the program that is jumped over, the jump destination can be displaced.
? The jump destination should be in the same segment or block as the jump statement.

Caution
Avoid jumps over block boundaries since you have no control over the absolute
location of blocks in the internal user memory.
