• Variables in the equation are listed in the order in which they appear in the
equation. Any values stored to the listed variables also are displayed.
• The default lower and upper bounds appear in the last line of the editor
(

• A $ is displayed in the first column of the bottom line if the editor continues
beyond the screen.

When you enter or edit a value for a variable in the interactive solver editor, the new
value is stored in memory to that variable.
You can enter an expression for a variable value. It is evaluated when you move to the
next variable. Expressions must resolve to real numbers at each step during the
iteration.
You can store equations to any VARS Y-VARS variables, such as Y1 or r6, and then
reference the variables in the equation. The interactive solver editor displays all
variables of all Y= functions referenced in the equation.
