And now...

This just gets you started. By now you should have learned enough for simple operations. However, like as not you will want more, such as how to build procedures for repetitive operations. So, you will have to read the full introduction to SPECX in this cookbook, or Rachael Padman's full SPECX manual. Also, experimentation is a good thing; the worst that can happen is a core dump (a large file called core will be created in your directory). You should delete this file if this happens.
