L KF +125

L MW 200
I 50
T MW 202 ;LOAD FROM DW FIELD DATA INPUT
B MW 200
L DW 0 ;TR.TO DW FIELD DATA INDICATION
B MW 202
主要不明白B 这个命令是什么意思?手册解释
B rs 60to63
Execute an operation whose operation code
is stored in the system data area (RS = free
system data: RS 60 to 63). In 2-word operations
the 2nd word must be loaded in RS n + 1.
根据手册解释,就是执行MW200中的代码,但MW200是125,这个125又是什么命令?真是着急
