JMP has a scripting function called JMP Scripting Language (JSL), which allows you to write scripts to reproduce the results of JMP analyses. Therefore, using JSL can be useful if you regularly perform a series of analyses or if you want to fit the same model to new data every day using the same procedure.
If you want to learn how to use JSL and see examples, I recommend the following:
1. Scripting Guide
The Scripting Guide provides basic information for JMP users who are new to the scripting language (terminology, syntax, etc.), as well as more advanced information. We recommend that you start by looking at the table of contents of the Scripting Guide and finding the section that best describes what you want to do.
2. Script Syntax Reference
The Script Syntax Reference contains descriptions of the functions and operators provided by JMP. Refer to this document for detailed syntax and examples of JSL commands.
3. Script Index
If you are using JMP, select Help → Scripting Index from the JMP menu to display the scripting index, where you can check the functions and other information you are interested in.
The following example shows the script index display for the Col Mean function in the Statistical category. You can run the example script by clicking the "Run example" icon (the icon to the right of "Example 1" in the figure below).

(For JMP 14 and later) The Script Index can be displayed by entering the desired function in the script window, right-clicking on it, and selecting Open Script Index from the menu that appears, as shown below. This allows you to quickly refer to the script when you need to know the syntax while creating a script.

4. JMP User Community Site
The JMP User Community site provides a variety of resources for JMP users, including discussion threads, though the content is primarily in English.
If you search in the search bar of the JMP User Community site by entering the word you are interested in along with JSL (for example, if you want to find examples of JSL scripts related to missing values, you would enter "JSL and missing" as shown below), the search results will display related discussion threads, and you may be able to view sample scripts and other materials within them.

Note: The JMP User Community site contains many useful content and some scripts that can be used as references, but we have not tested all of these scripts. If you use them for reference or for actual use, please test them beforehand and use them at your own risk.
Please also note that inquiries regarding the content of posts on the JMP User Community site are not, as a general rule, the subject of technical support.
