Expression
Input − [ A FG (n) B → C ]− Output
Function
When the input is ON, this instruction finds the function value f(x) for A as x, and stores it in C. The function f(x) is defined by the parameters stored in 2 ⋅ n registers starting with B.

Example
When R010 is ON, the FG instruction finds the function value f(x) for x = XW004, and stores the result in D0100.
The function f(x) is defined by 2 ⋅ 4 = 8 parameters stored in D0600 to D0607. In this example, these parameters are set at the first scan.
