• Saving Scripts and Working with Automatic Scripts

  Scripts are typically meant to be run repeatedly over time, and possibly in different situations. In order to maximize the flexibility of scripts, JMP provides several ways for you to save them. You can save a script in a standalone JSL source code file and then open it and run it from the Script Editor or the Debugger. You can save a script to the data table or as a data column formula...

• Automatic Script Generation

  A great feature of JMP is that it can generate a script for you from an existing object, like a data table or an analysis platform. This can be really helpful. One thing it lets you do is exactly repeat an analysis after some change to the data, either now or in the future. Or, if you perform a series of analyses and have JMP save those scripts to the data table, you can share the data ...

• Creating Scripts Automatically and Saving Scripts

  So this demonstration, we'll look at the various ways that you can create and save JMP scripts. So I'll begin by interactively creating a new column with a formula where I calculate the standardized value of the tensile strength of concrete. So in the journal in section I'll click Concrete Strength Data. So to create my new column of the standardized strength, I'll go to the Columns men...

• Overview Basics

  In order to write your own scripts, you need to familiarize yourself with the elements that a script can contain: names, variables, functions and operators, numbers, character strings, punctuation, and comments. Let's take a look at each of these in turn.

• Names

  Names are important in JMP, and especially in scripting. In fact, everything in JMP has a name! This includes objects, menu commands, functions, and messages to objects. And the variables in your scripts also have names. Names have to follow certain rules or syntax. A name has to start with either an alphabetic character--A through Z, lowercase or uppercase--or an underscore. So, names ...

• Variables

  OK, so now let's talk about variables. You can use variables to store values that aren't constant from one time a script runs to another. These values can be data of any type, data structures of any kind, or references to another object. Unlike in many programming languages, JMP variables don't need to be declared, or listed at the start of the script, and they're not limited to storing...

• Creating Variables

  OK, so let's look at a few examples of creating variables. Suppose you want to create a variable named a, and you want to assign the value of to it. This assignment statement (a = creates a global variable with the value of What if you want a local variable named a? To create a local variable, you use the Local function, which takes two arguments: the first argument is a name or list of...

• Functions

  Functions are a vital element of the scripting language, so let's discuss them. You call a function when you need it, and every function returns a result. To call a function, you type the function name followed by two matching parentheses -- the matching parentheses are what tells JMP that a name is a function. For example, Names Default to Here followed by matching parentheses that con...

• Combining Functions

  So, it might surprise you to learn that every script is actually a single function along with its arguments. And it might seem at first like this requirement would limit how much a script can do. But remember that a function can have arguments and that some of those arguments can be functions as well. For example, you might want to add the square root of to the sine of The Add function ...

• Numbers

  Numbers are an essential form of data, and can be expressed as integers, decimals, or in scientific notation. Dates and times are also represented by a number. A missing numeric value is represented by a period. Let's go into a little more detail about dates, times, and durations. These are all numeric values that represent a number of seconds. Specifically, dates are defined as the num...

• Character Strings

  Some data are text that are represented by character strings. Character strings are delimited by double-quotation marks, and these delimiters are not part of the text. So, what if you need to include double quotation marks as part of your string value? To do that, each of the embedded quotation marks has to be preceded with the escape sequence of a backward slash and an exclamation poin...

• Punctuation

  Now let's talk about punctuation in your scripts. Commas separate items-- they separate items in lists, rows in matrices, and arguments in a function or message. Parentheses serve several purposes. They're used to identify a name as a function. They surround the arguments of a function. And, they can control the order of evaluation in expressions.

• Comments

  Next, let's talk about comments. It can be really helpful to include comments in your scripts. Comments aren't executed when the script runs, so they could be notes to yourself (for example, documenting the script for future updates or maintenance), or they could be notes to others who might use your script (providing instructions, for example). You might also comment out a portion of y...

• Working with Local Variables

  Well now, let's take a quick look at local variables and using the local function. So I'm going to clear the contents of the Script Editor and I'm going to type local and open parentheses. And recall that the first argument is a list of the local variable names and I can either make the assignments in that list or that could be part of the JSL expression that is the second argument to t...

• Using Date and Time Functions

  So next, let's talk a little bit about date and time functions. I'm going to clear the contents of the Script Editor window. I'd like to clear the log as well. And I do that by right clicking in the Log window and selecting Clear Log. So remember that dates and times are stored as the number of seconds since midnight January And you can store those in a variable. And we can also use dat...

• Using the Log

  So we've been making use of the log to look at the results of all of the lines of code that we've run. But we can also control what shows up in the log. So let me clear that and clear the Script Editor window. So one thing I could do, if I am working with global variables, which, of course, I have been, is I can type show globals open close parentheses. I don't have to have an argument,...

• Objects and Messages

  Now let's discuss the concept of objects. Many of the capabilities of JMP are available to your script through built-in objects. Every JMP object knows how to perform certain actions or tasks. And some examples of JMP objects are data tables, data columns, platforms, and even JMP itself. Now in order to use an object in your script, the script first needs to instantiate the object, or c...

• Introduction to Lists

  An important data structure in JMP is a list, which is a general-purpose storage container that can store any number of items. The items can be any type of data such as numbers, character strings, object references, or other lists, and the items in the list don't need to be the same type. You can create a list with the List function, or with the curly brackets operator. Items in a list ...

• Working with Lists

  Lists are dynamic. You can easily add items to or remove items from a list as necessary. You use the Insert function or the Insert Into function to add items to a list. By default, the items are added at the end of the list. Optionally, you can include an argument to specify the position of the item you're adding. The Insert function returns a new list with the added item but doesn't ch...

• Introduction to Matrices

  Another useful data structure is a matrix, which is a rectangular array or table of numeric values or missing values. You can use a matrix to store a single number, a column of numbers, (sometimes called a column vector,) a row of numbers, (or row vector,) or an entire table of numbers. A matrix can be empty -- that is, have no rows or columns. An empty matrix can be useful for collecti...

• Working with Matrices

  You can use the Matrix function to create a matrix. And this function takes a list of lists as its argument, where each sub-list specifies a row. You can also use the square brackets operator to create a matrix. When you use this operator, you enter the values directly, without using lists. Instead, you separate the values in different rows with commas, and the values in different colum...

• Using Lists and Matrices

  So this demonstration is going to look at some of the basic features of lists and matrices. So I'm going to start with lists. And I'm going to get a new script editor window. So again, the keyboard shortcut is Ctrl+T. And I will resize and rearrange that. Let me go ahead and bring the log in front of the journal. And I'm going to create a variable I'll call my list. And I'll assign that...

• Style Tips for Scripts

  So, although your scripts follow a strict syntax, there's no strict style imposed by JMP in the scripting language. Remember that JMP ignores whitespaces and letter case. So, style, then, is important for legibility. Let's take a look at an example. The script shown here follows the syntax rules and will run correctly. But the style -- or lack of style -- make it difficult to read and u...

• Overview of Iteration

  Scripts are procedural. In other words, JMP evaluates a script beginning with the first line and continuing until the last line. Some scripts require JMP to repeat an action multiple times. But you don't repeat the code for that action in your script for every time you want JMP to perform the action. Instead, you use special iteration functions to repeat that portion of the code. In som...

• Using the For Function

  So, the For function provides the most general form of iteration. This function has four required arguments, and each one is a JSL expression. And as usual, these four arguments are separated by commas. JMP evaluates the first argument to the For function only once. Generally, you use this first argument to initialize a variable that you can use as a counter, or index, in each iteration...
