Talk:P-code machine
From Wikipedia, the free encyclopedia
There seems to be a lot of vagueness here as to whether p-code is a generic term or a specific encoding. Which is it? Nentuaby 07:14, 10 June 2006 (UTC)
"In computer programming, a virtual machine executing p-code." That sentence doesn't even make sense! I'm going to change it to something better MichaelBillington 00:52, 2 April 2006 (UTC)
Infact, the whole opening paragraph is filled with senseless jargon MichaelBillington 00:53, 2 April 2006 (UTC)
1. Changed "P-code was the target of early compilers" to "P-code was the target of some Pascal implementations". Not all early Pascals were interpreted. The first CDC 6000 implementation was not, nor the IBM 360 implementation and several others. In fact, UCSD was the only one until a few UCSD imitators showed up. I changed the "compilers" part because it wasn't a true compiler.--192.18.42.11 29 June 2005 22:59 (UTC)
"In computer programming, a P-code machine or pseudo-code machine is a specification of a cpu whose instructions are expected to be executed in software rather than in hardwar. " - "There seems to be a lot of vagueness here as to whether p-code is a generic term or a specific encoding." I cannot agree more. From the first sentence, it seems there can be many types of P-code machines. But then later it seems that there is only one. For example, "The p-Code machine is stack-oriented." _The_ p-Code machine? Only one? So, a machine that is not stack-oriented cannot be _a_ p-code machine? [User:M K Lai] 6 Jan 2007
[edit] IP Issues?
The popular implementations i'd heard about were commercial I've read about USCD licencing P-System to Pecan etc. What I've never understood is exactly what was being licensed. Was it specific implementations or did P-Code instelf have some sort of intellectual property protection Were there ever any unencumbered (public domain, etc) implementations? What affect did this have on it's popularity? —The preceding unsigned comment was added by 68.38.203.239 (talk) 14:34, 29 January 2007 (UTC).
[edit] Pascal implementation
Is it intentional that the "instruction" type definition is missing from the Pascal implementation of p-code included on the page? Espertus 13:57, 13 March 2007 (UTC)
[edit] Cleanup: inconsistent capitalization
The capitalization of "p-code"/"P-code"/"p-Code" is inconsistent, perhaps because people are referring to specific implementations that used different capitalization. Espertus 14:02, 13 March 2007 (UTC)
