plz explain "two way interpreter" Cheers Rolf ( addicted to the Perl Programming Language) ps: Then plz see How do I post a question effectively? `First and foremost, think through your question. Can you explain it clearly to yourself? Can you explain it to others? What example data would help them understand the issue?

G'day pankaj verma, Welcome to the monastery. "perlmod: BEGIN, UNITCHECK, CHECK, INIT and END" may be sufficient for your needs. It contains an example script that reports what's happening from where the interpreter starts the compilation phase (`BEGIN`); the various stages between the compilation and execution phases (`UNITCHECK`, `CHECK` and `INIT`); through runtime to where the interpreter exits (`END`). If you're after more technical details, see the links in "perl: Internals and C Language Interface". You'll find the perlinterp link, recommended by LanX above, in this section. -- Ken	[reply] [d/l] [select]

Every interpreter is pretty-much the same: the source-code is assimilated (from its various origin files) and parsed to create an internal data-structure which is then what drives the `perlguts` of the interpreter itself. When you read about "compile-time," that's the time spent building that structure.	[reply]
