One of the most notable uses of P-Code machines is the P-Machine of the Pascal-P system. The developers of the UCSD Pascal implementation within this system construed the P in P-code to mean pseudo more often than portable; they adopted a unique label for pseudo-code meaning instructions for a pseudo-machine.
Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...

Most East Asian characters are usually inscribed in an invisible square with a fixed width. Although there is also a history of half-width characters, many Japanese, Korean and Chinese fonts include full-width forms for the letters of the basic roman alphabet and also include digits and punctuation as found in US ASCII. These fixed-width forms ...
This performance advantage was eroded by the later availability of p-code to native machine code translators, and mainstream 16-bit microprocessors such as the Intel 8086 and Motorola 68000. When details of the MicroEngine were first released, the system accumulated a very large number of pre-orders (for the time).
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
The book was used as the textbook for MIT's former introductory programming course, 6.001, [5] from fall 1984 through its last semester, in fall 2007. [6] Other schools also made use of the book as a course textbook. [7]
Joel McCormack is an American computer scientist who designed the NCR Corporation version of the p-code machine, which is a kind of stack machine popular in the 1970s as the preferred way to implement new computing architectures and languages such as Pascal and BCPL.
