Assignment Functions
Figure B.18 Example of a Formula Using the Selected Function
The example in Figure B.19 assigns row state conditions to a row state column. The formula for the row
state column (in the columns called row state col) checks to determine whether the active row state is either
Hidden or Excluded, and if so, assigns the Labeled row state.
Figure B.19 Calculate Row State Information in a Row State Column
Color Of
Accepts any row state expression or column, or the Row State() function as its argument. Returns a number
from the JMP color map that corresponds to the active color state, or zero if there is no assigned color.
Marker Of
Accepts any row state expression or column, or the Row State() function as its argument. Returns a number
from the JMP marker map that corresponds to the active marker or zero if there is no assigned marker.
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. You
can use the Formula Editor to create and execute a script in that column, but this is not recommended
because of dependencies and ambiguities that can result. Most often, scripts are stored as .jsl files, and can be
saved with a data table. See “Create and Save Scripts” on page 124 in the “Enter and Edit Data” chapter. For
details about syntax, see the Scripting Guide.
Note: The first argument of an assignment function must be capable of being assigned. This means you
cannot have an assignment such as 3+=4, because 3 is a constant value that cannot be reassigned. You must
first create a variable (a table variable or local variable) whose value is 3. (For details about table variables, see
“Use Table Variables” on page 122 in the “Enter and Edit Data” chapter. For details about local variables, see
