The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

A reader, that somewhere along the line does some parsing :-)
Uh, the technical term for the "lexical" stage, that recognizes tokens
in an input stream, and passes them to a parser, is "scanner."
The lexical stage is the scanner.
The syntactic stage, which is usually in overall control, is the parser.
The semantic stage is either a code generator, or a direct executive.
That is about as fundamental as compiler theory gets.
And BTW, I can tell you from experience that it is entirely possible to
write a recursive descent parser in ILE RPG. I've done at least two myself.
