>>"P-code works by compiling an application into an intermediate code format that is much more compact than 80x86 machine code. At link time, a small engine is built into your application that processes the p-code into native machine code during run time. Although there is an associated reduction in performance due to the extra step of interpretation, some simple techniques can minimize this effect."

I realised that the technology wasn't the same, though the principle is - first the high-level language is compiled to p-code & that p-code is interpreted.
