# 5.3 Including data within command scripts

It is also possible to embed data directly within Pyxplot scripts, which may be useful when a small number of markers are wanted at particular pre-defined positions on a graph, or when it is desirable to roll a Pyxplot script and the data it takes into a single file for easy storage or transmission. To do this, one uses the magic filename `--` and terminates the data with the string `END`:

    plot '--' with lines
    0 0
    1 1
    2 0
    3 1
    END
    print "More Pyxplot commands can be placed after END"
