ExST Assignment ‘S=’¶

This operator sets a variable. Once the value of the variable to the left of S= has become TRUE, it remains TRUE even if the operand to the right of S= goes FALSE again.

<variable1> S= <variable2>;

Example

bVar1 S= bVar2;

bVar1 obtains the value of bVar2. Once bVar1 has been set to TRUE, bVar1 remains TRUE even if bVar2 becomes FALSE again.

Hint

Multiple assignments All set and reset assignments always refer to the last term of the assignment. Example: a S= b R= fun1(par1,par2); In this case b receives the output from fun1 resulting from the reset, but: a does not receive the set result from b, but the set result from fun1!
