Re: p-code compilers

Hi,
just two remarks:

: Java generates p-code, using its compiler. The p-code is then
: interpreted by the Java Virtual Machine. Both Java and the JVM are
: translators of different types.

Java is a language and therefore neither translator nor compiler.
Confusing these concepts often leads to sentences like "Java is
slowier than C++", or "This compiler is faster than that" ( when speed
of generated code is meant).


: By the way, p-code is different from pseudocode. Pseudocode is a
: natural language based method of describing an algorithmn. P-code is
: virtual machine code. The original p-code was developed for Pascal.
: I suppose that's why it's called p-code.


and, as a fact, P-code differs from J-Code, and P stands for Pascal,
while J for Java (who would expect that ;-) ). There are much more so
called intermediate languages, as these are commen to enable an easier
translation/compilation process especially at the beginning of the
life of a language.
