Purpose The include statement is used to include code in other files into a Superx++ program. This allows for partitioning of large programs into files of manageable sizes.
Format include({file path});

include({file path}) {
      {finder expr}

{file path} the path to the file with the Superx++ code to be include
{finder expr} the expression to be used to find the set of objects within the file to be included-- this allows for partial inclusion
Example #1 include("C:\\MyDir\\MyFile.xml");

This will include all the contents of the file found at C:\\MyDir\\MyFile.xml. This kind of inclusion where the whole contents of a file are included into the program is common in other languages. You might call it complete inclusion.

Example #2 include("http://MyServer/MyDir/MyFile.xml") {
      has node:class and attr:name=XPlant

This will include only the class statement defining the XPlant class within the file found at http://MyServer/MyDir/MyFile.xml. If there are other statements in the file then they are not included. This is called partial inclusion.

Example #3 if (kind = "partial") {
   include("http://MyServer/MyDir/MyFile.xml") {
      has node:class
} else {

This will include all the class statements within the file found at http://MyServer/MyDir/MyFile.xml because the parameter kind is set to partial. If kind had a different value then the entire contents of the file would be included instead. This run-time determination of what gets included (or in a different example, you could make it include different files entirely) is called conditional inclusion.
