C.2.2. - Upper-case letters
The upper-case letters
A to
Z represent single-valued
variables.
They retain their values on subsequent calls to
calc.4.
Variables can appear on either side of an equation.
For instance,
you may have:
fn calc.4 A = 1.4; B = 4.4e-2; C = 3.22e-4 fn . y = A*x + B*x*x + C*x*x*xor
fn calc.4 n = 101; W = i*pi/50; x = cos(W); y = sin(W)Assignment to variables only occurs if the number of current points is nonzero. If you have no current points, you may use
n = 1
to force evaluation of your expressions.
