Rules for Name Resolution
In JMP, you identify the following types of objects by a name:
•
Columns and table variables in a data table
•
Global variables, which hold values for the remainder of a JMP session
•
Scriptable object types
•
Arguments and local variables inside formulas
Most of the time, you can just use an object’s name directly to refer to the object. Consider the following example:
ratio = height / weight;
Depending on the complexity of your script, it might be obvious that ratio is a variable and height and weight are data table column names. But what if the meanings are ambiguous? A script might use ratio as a global variable and as column names.
