Get
 Usage
• <<name reads in a file, evaluating each expression in it, and returning the last one.
Notes
• On systems with graphical interfaces, there will usually be graphical tools for reading in files. • If name is the name of a Mathematica context, ending with a ` context mark character, then Get will process this name to find the file to read. • If name is the name of a file, any .m extension must be included explicitly. • Get can read .mx files of Mathematica definitions written by DumpSave. • <<"name" is equivalent to <<name. The double quotes can be omitted if the name is of the form specified in Section A.2.7. • If a file with name file.mx is found to be a directory, Get will look for a file with a name like file.mx/$SystemID/file.mx. • If the file found by <<name is a directory, Mathematica will try to load the file init.m in that directory. • Get by default successively searches for files in the directories specified by the elements of $Path. • Get[name, Path->{" ", " ", ... }] successively searches for files in each of the  . • Syntax errors in Mathematica input files are reported in the standard form: filename: line: syntax error in expr. Get continues attempting to read a file even after a syntax error has been detected. However, if an error is detected, $Context and $ContextPath are reset to the values they had when Get was called. • During the execution of Get, the global variable $Input is set to the name of the file being read. • Get["file", "key"] reads a file which has been encoded using Encode["source", "file", "key"]. • New in Version 1; modified in 3.
