### 4.7.2 Reading files

If you have a function or other Xcas information in a file, you can load it with the read function. If the file is named myfunction.cxx, then

> read("myfunction.cxx")

will load the file, as long as the directory is in the current working directory. If the file is in a different directory, you can still load it by giving the path to the file,

> read("/path/to/file/myfunction.cxx")

While read can be used to load files containing Xcas functions, which typically end in .cxx, if you want to load a saved session you should use the load function;

> load("mysession.cas")
