Explanation of symbols:
x compare operator vop 1) Not at CL 800 level
0: . . . . no condition 2) ”Condition”: a)
Var =Boolean variable
1:= . . . . equal to b)
Var . Const =Bit from pattern
2: . . . . not equal to c)
Var ”Vop” Value
3: . . . . greater than d) Extended condition
4: = . . . . greater than or equal to
5: . . . . less than 3) Option
6:= . . . . less than or equal to
7: . . . . true 4) No pointers possible,
8: . . . . not on CL 800 level only
