ucsd pascal การใช้

• Turbo Pascal syntax for units appears to have been borrowed from UCSD Pascal.
• UCSD Pascal was later adopted as Apple Pascal, and continued through several versions there.
• UCSD Pascal was first released in 1978.
• The first five games in the series were written in Apple Pascal, an implementation of UCSD Pascal.
• JRT was able to get considerable attention for several months by being a much cheaper alternative to UCSD Pascal.
• UCSD Pascal branched off Pascal-P2, where Kenneth Bowles utilized it to create the UCSD p-System.
• UCSD Pascal used an intermediate code based on byte values, and thus was one of the earliest " byte code compilers ".
• They were ported to many different platforms by writing UCSD Pascal implementations for the target machines ( Mac II cross-development ).
• The Sage itself was initially developed using UCSD Pascal and p-code, so it fitted well with the basic BOS design.
• This idea originated as early as in the late 1970s, when the UCSD Pascal system was developed to produce and interpret p-code.
• There are many historical examples of code running on virtual machines, such as the language UCSD Pascal using bytecode executed by the Java virtual machine.
• And by easily programmed personal workstations with raster graphics such as the Terak 8510 / a UCSD Pascal machine and the high performance PERQ Unix system.
• The Pascal MicroEngine ( 1979 ) was designed for the UCSD Pascal form of p-code ( Pascal compiler bytecode ) as its machine code.
• UCSD Pascal, under Professor Kenneth Bowles, was based on the Pascal-P2 kit, and consequently shared several of the Pascal-P language restrictions.
• Separate compilation was not part of the standard Pascal language, but was already available in UCSD Pascal, which was very popular on 8-bit machines.
• UCSD Pascal ( along with the Smalltalk virtual machine ) was a key influence on the design of the Java virtual machine, as is cited by James Gosling.
• Although UCSD Pascal actually expanded the subset Pascal in the Pascal-P kit by adding back standard Pascal constructs, it was still not a complete standard installation of Pascal.
• The Borland dialect, like the popular UCSD Pascal before it, took the'P4'version of the language as its basis, rather than Wirth's final revision.
• The IBM PC versions of the language began to differ with the advent of UCSD Pascal, an interpreted implementation that featured several extensions to the language, along with several omissions and changes.
• An earlier programming language, UCSD Pascal, attempted to run transparently on many different kinds of computers, but because of the necessity of being all things to all people, its performance lagged.
