Re^3: perl language by Anonymous Monk on Nov 12, 2007 at 17:48 UTC
So Perl is like java which is compiled and interpreted and c is compiled-linked and run by the processor.. That makes sense.. Usually, when a lot of brute-force processing needs to be done, you want to avoid virtual machines, and get right to the hardware, preferably with a language which can generate very good machine code, e.g., when you need to run a 1,000,000 DOF finite-element model, large-scale n-body simulations, or climate modeling, saving a few nanoseconds per computation can really add up. Most tasks aren't anywhere near that computationally intensive. "Interpreted" also sometimes seems to mean "entered into an IDE which continually checks syntax," with "compiled" meaning "completely entered into a file, which is then passed through a 'compiler' or 'interpreter'." By this, I mean something like this: (> indicates what person enters; < indicates what system returns) `<PIRNT 'Today is Tuesday' >PIRNT NOT RECOGNIZED <WRITE 'Today is Tuesday' >WRITE NOT RECOGNIZED <PRINT 'Today is Tuesday' >Today is Tuesday <QUIT` [download] ciao	[reply] [d/l]
