Path variables are shortcuts to directories or files. Rather than enter the entire path to the directory or file, you use the path variable in a JSL script. A path variable is a special type of string and is always contained within double quotation marks.
One common predefined path variable in JMP is $SAMPLE_DATA. This variable points to the sample data folder in your JMP or JMP Pro installation folder. The following example opens the Big Class.jmp sample data table.
Open( "$SAMPLE_DATA/Big Class.jmp" );
Several path variables are predefined in JMP. The following table shows the definitions for the current JMP version. Variables in previous versions of JMP might differ.
|
Variable |
Path |
|---|---|
|
ADDIN_HOME(com.your.addin.id) Defines the folder where the specified add-in is stored. |
Add-In Builder stores the specified add-in in the following folders, based on your operating system: • Windows: C:\Users\<username>\AppData\Roaming\SAS\JMP\Addins\ • macOS: /Users/<username>/Library/Application Support/JMP/Addins/ For example, Convert File Path( $ADDIN_HOME(com.your.addin.id) evaluates to the location of the com.your.addin.id add-in. To install your add-ins in a shared network location, use the Register Addin() function. See Register an Add-In Using JSL. |
|
ALL_HOME Defines a folder that can be accessed by all users on a machine. |
• Windows (JMP): C:\ProgramData\SAS\JMP\17\ • Windows (JMP Pro): C:\ProgramData\SAS\JMPPro\17\ • macOS: /Library/Application Support/JMP/17/ To see if the directory exists, run the script Is Directory("$ALL_HOME");. If the folder exists, 1 is returned. |

Path variable definitions are updated automatically based on the version of JMP you are using. For example, when you run a JMP 14 script in JMP 17, the JMP 17 path variable definitions are used.
To see the definition of any path variable, use the function Get Path Variable:
Get Path Variable( "HOME" );
"/C:/Users/<username>/AppData/Roaming/SAS/JMP/17/"
Note that you don’t include a dollar sign for Set Path Variable() or Get Path Variable(). But you must include the dollar sign when using the variable in a script.
Make sure to include a trailing slash after the path variable. In the following example, the root name "Big Class" is assigned to the dtName variable. The Open() expression evaluates $SAMPLE_DATA and the trailing slash and then appends the dtName value along with the file extension .jmp.
dtName = "Big Class";
dt = Open( "$SAMPLE_DATA/" || dtName || ".jmp" );
The path is interpreted as:
C:\Program Files\SAS\JMP\17\Samples\Data\Big Class.jmp
Without the slash that follows $SAMPLE_DATA, the path is interpreted as:
C:\Program Files\SAS\JMP\17\Samples\DataBig Class.jmp
