4.1.3  Reading files

Information for Xcas can be stored in a file; this information can be read with the read command, depending on the type of information.

The read command reads a file containing Xcas information, such as a program that you saved (see Section 2.6.3) or simply commands that you typed into a file with a text editor. The file should have the suffix .cxx.

• read takes filename, the name of a file (a string) containing a saved program (see Section 2.6.3) or other commands.
• read(filename) reads the content of the file.

Examples

If you have a file named myfunction.cxx,

In Windows, you should use \\ instead of / as the directory separator. In Linux, absolute paths usually begin with /home/.
