N多年前学的编译原理，一点印象也没有了。
Java,VB,C# 这些语言是先编译成Pcode，然后在执行的。
但是，Pcode是像汇编语言一样的东西呢？还是只是一个 execution stack？

p code is only used for pascal ... similar to JVM though.
it's an instruction set defined on a stack based machine.
( i.e. there are no registers in this machine, therefore ISA is much simpler)

Java, VB什么也用的。。 jvm是一个运行环境，pcode在里面运行成机器代码

carrying a knife doesn't mean that she is going to slash someone.

jvm is also a stack based machine, but its instruction set is more
complicated,
for example, it has exception throwing instruction, which i'm sure p-code
doesn't have.

you're correct, as always. =)
but the intend is there, no?
