Assignment Functions
Assignment Functions
Assignment functions work in place. That is, the result returned by the operation (on the right of the
operator) is stored in the argument on the left of the operator and replaces its current value.
Assignment statements are most often used in conjunction with other commands to build a JSL script.
See the JMP Scripting Guide for details about syntax.
= (assign) Puts the value of b into a. For example, (a=b).
+= (add to) Adds the value of b to a and puts the result back into a. For example, a+=b.
-= (subtract to) Subtracts the value of b and puts the result back into a. For example, a–=b.
*= (multiply to) Multiplies b with a and puts the result back into a. For example, a*=b.
/= (divide to) Divides b into a and puts the result back into a. For example, a/=b.
++ (post increment) Adds one (1) to a, in place, so that a++. For example, if the initial value of a
is 4, the expression a++ changes a to 5.
-- (post decrement) Subtracts one (1) from a, in place, so that a– – . For example, if the initial
value of a is 4, the expression a– – changes a to 3.

Parametric Model Functions
This category is a short cut to create three parametric models that are linear functions of set of
window-selected columns.
Linear Model, Interactions Model, Full Quadratic Model
Selecting each of these opens a column selection box that lets you select one or more columns to be
included in the model. The function then creates and populates the chosen model.
