各位老师好：
最近研究程序，其中一个程序中这样写：
A "逻辑运算1"
= L 5.0
A L 5.0
A "+S-156K1"
= L 0.0
A L 5.0
A "+S-416K1"
= L 0.1
A L 5.0
A "+S-426K1"
= L 0.2
A L 5.0
A "+S-136K1"
= L 0.3
A L 5.0
A "+S-146K1"
= L 0.4
A L 5.0
A "+S-126K1"
= L 0.5
A L 5.0
A "+S-166K1"
= L 0.6
A L 5.0
A "+S-176K1"
= L 0.7
A L 5.0
A "A 20.5"
= L 1.0
A L 5.0
A "逻辑运算0"
= L 1.1
A L 5.0
A "逻辑运算0"
= L 1.2
A L 5.0
A "逻辑运算0"
= L 1.3
A L 5.0
A "逻辑运算0"
= L 1.4
A L 5.0
A "逻辑运算0"
= L 1.5
A L 5.0
A "逻辑运算0"
= L 1.6
A L 5.0
A "逻辑运算0"
= L 1.7

我想问一下，其中的L0.1 L0.2什么的，是什么东西？起的作用是什么？
