I've searched around and haven't found any simple way to get System Preferences settings from within JSL.  I'm developing on a Mac – (JMP 14 & 15) – but would also like to know how to do this on Windows.  The closest I got was a <a href="https://community.jmp.com/t5/Discussions/Manage-the-display-language-with-JSL-or-freezing-english/td-p/236566" target="_self">discussion</a> on how to get the language code: <pre><code class=" language-jsl">System Service( Get Language Code );</code></pre><code class=" language-jsl">System Service</code> sounds like and interesting function, but I couldn't find any documentation on it.  I'm looking for a general solution but am immediately interested in finding the date format, (per setting in System Preferences ➔ Language & Region ➔ Advanced... ➔ Dates ➔ Short), as shown below: <li-image width="419" height="304" alt="Screen Shot 2020-07-20 at 5.55.13 PM.png" align="inline" id="25579iA7A4C74EE827C951" size="large" resized="true" sourcetype="new"></li-image>The Short date delimiters are normally set to slashes by default, but were modified by me to dashes in the image above.  The specific issue I find with changing this setting is that it affects what arguments are valid to the <code class=" language-jsl">Input Format</code> function.  For example, the following statement will generate a runtime error: <pre><code class=" language-jsl">col << Input Format( "y/m/d h:m:s" );</code></pre>So the code must instead look like:<pre><code class=" language-jsl">col << Input Format( "y-m-d h:m:s" );</code></pre>And the reverse it true if the user has their System Preferences set to slashes.  Furthermore, with the <code class=" language-jsl">Format</code> function, if the wrong date string is given, there won't be a runtime error, but the relevant datetime column will ignore the format setting, and the data will be left in its raw, unintelligible form. Thus, the set of valid arguments are dependent on the user's setting, and the code must first read this setting to determine which format to use. As a workaround, I was able to collect the settings information from a system Unix command and parse it accordingly: <pre><code class=" language-jsl">// implement Unix command: // $ defaults read com.apple.mail DateCellWidthCache | grep M.d.yy Clear Log(); // read System Preferences from 'defaults' that contains date format string. sDefaults = Run Program( Executable( "/usr/bin/defaults" ), Options( { "read", "com.apple.mail", "DateCellWidthCache" } ), Read Function( "text" ) ); //Write( sDefaults ); ss1 = Munger( sDefaults, 1, "M/d/yy" ); // check for slash style. ss2 = Munger( sDefaults, 1, "M-d-yy" ); // check for dash style. Show( ss1, ss2 ); Write("\!n"); If( ss1 > 0, Write( "Using slashes.\!n"); , /* else if */ ss2 > 0, Write( "Using dashes.\!n"); , /* else */ Write( "***ERROR: unrecognized date delimiter.\!n"); Write( "defaults read com.apple.mail DateCellWidthCache:\!n"); Write( sDefaults ); );</code></pre>However, this seems a bit clumsy, and I imagine there's a simpler way.  It's apparent that the JMP engine can read this setting as it presents a very different set of time formats in the Column Properties dialog based on this setting, as shown below (presenting only the dash options here): <li-image width="362" height="597" alt="Screen Shot 2020-07-20 at 6.30.49 PM.png" align="inline" id="25580i8912953604D384AD" size="large" resized="true" sourcetype="new"></li-image>So, my question is:  Is there a simple way to get arbitrary System Preferences values (and the date format specifically) by using <code class=" language-jsl">System Service</code> or some other function?
