Simple Blocks

Blocks are Glee's stored program elements. Everything between curly braces ({...}) Glee takes as code for the block. Blocks in Glee are objects just like other Glee elements. Code is just one of a block's several members. Others are its namespace, its initial expression, its break expression, and its error expression. For a general description of this tutorial, press Commentary.
