===The <codett>ENVIRON</codett> and <codett>USING</codett> clauses.===

These clauses are kind of the ''inverse'' of the '''#include''' found in the [[C (programming language)|C programming language]], or '''import''' found in [[Python (programming language)|Python]]. The purpose of the <codett>ENVIRON</codett> mechanism is to allow a program source to be broken into manageable sized pieces. Note that it is only necessary to parse the shared source file once, unlike a '''#include''' found in the C (programming language)|C programming language where the include file needs to be parsed for each source file that includes it.

* <codett>MODE STRING</codett> implemented without FLEX.
