Pascal Tutorial  

     

  1. Pascal Programming Basics
    In a program, you must always obey the rules of the language, in our case, the Pascal language. A natural language has its own grammar rules, spelling and sentence construction. The Pascal programming language is a high level language that has its own syntax rules and grammar rules. As you go along with the lessons, you must note what you can do and what you cannot do in writing a Pascal program.
    Program Lesson1_Program1; 
    Begin 
    Write('Hello World. Prepare to learn PASCAL!!');
    Readln; 
    End.
        
  2. What is Essential Pascal
    Essential Pascal" is a free online introduction to the Pascal programming language. This book has been written by Marco Cantý and covers the language form the perspective of Borland's Delphi development environment. You can find more information about this book in its introduction. The book is free, but writing takes a lot of time. I'm very happy to see my efforts payed back by 5 Euros out of your pockets, it's a way to puch me to keep the book up to date over time. 
       
  3. Learn Pascal
    This tutorial is an introduction to the Pascal simple, yet complete, introduction to the Pascal programming language. It covers all of the syntax of standard Pascal, including pointers. I have tried to make things are clear as possible. If you don't understand anything, try it in your Pascal compiler and tweak things a bit. Pascal was designed for teaching purposes, and is a very structured and syntactically-strict language. This means the compiler will catch more beginner errors and yield more beginner-friendly error messages than with a shorthand-laden language such as C or PERL. This tutorial was written for beginner programmers, so assumes no knowledge. At the same time, a surprising number of experienced programmers have found the tutorial a useful reference source for picking up Pascal. 
       
  4. Pascal Programming Tutorial
    This site offers write-ups of how to do specific things in Pascal. You don't need to pay for a compiler: the tutorials are based on a good free one. (No, "good" and "free" are not mutually exclusive!) The material should be of general use, but is, I hope, especially useful for those who have the Pascalite microcontroller. Feel free to use the tutorials in programming courses, but a credit of the source would be appreciated. You do not have to have the Pascalite hardware to do everything in these programming tutorials. IF YOU DO have the hardware, especially if you have just obtained it, PLEASE have a look at my Using the Pascalite Hardware It has details of how to access various features of the splendid Pascalite.
      
  5. Roby's Pascal Tutorial Contents
    I use Borland Pascal 7.0 for the code. If you using other compiler, say, Microsoft QuickPascal, you may do a slight modification. Still, you cannot review the Borland-specific lesson, like using BGI and so on. However, the concepts is all the same. Don't worry. I plan to divide the tutorial into 4 courses .It tells you about the basic structure, branches (if,case..of), constants, loops (for, while..do, repeat..until), procedures and functions, arrays, records, string manipulation, enumerated types, sets, get the most of crt unit, making custom unit, text, typed, and untyped files. 
      
  6. The GNU Pascal
    The free 32/64-bit Pascal compiler of the GNU Compiler Collection (GNU CC or GCC). It combines a Pascal front-end with the proven GCC back-end for code generation and optimization. Other compilers in the collection currently include compilers for the Ada, C, C++, Objective C, Chill, FORTRAN, and Java languages. Unlike utilities such as p2c, this is a true compiler, not just a converter. This version of GPC corresponds to GCC version 2.8.1, 2.95.x, 3.2.x, 3.3.x or 3.4.x. 
       
  7. The GNU Pascal Manual
    GPC's new or changed features since the last (non alpha/beta) GPC release are listed here. Items without further description refer to new routines, variables or options. Features implemented for compatibility to other compilers are marked with, e.g., (B) for BP compatibility. 
    A few old and obsolete features have been dropped or replaced by cleaner, more flexible or otherwise more useful ones. This might lead to minor problems with old code, but we suppose they're rare and easy to overcome. Backward-incompatible changes are marked with (@). 
       
  8. Pascal Programming
    PASCAL is a programming language named after the 17th century mathematican Blaise Pascal. Pascal. provides a teaching language that highlights concepts common to all computer languages and standardises the language in such a way that it makes programs easy to write 
    Strict rules make it difficult for the programmer to write bad code.program is the first word of all Pascal programs. It is a keyword (Keywords are reserved, ie, you cannot use keywords to describe variables). TITLE is the name the programmer gives to the Pascal program being written. It is an identifier. Identifiers begin with a letter, then followed by any digit, letter or the underscore character ( _ ). 
      
  9. General Pascal Information
    In MS-DOS, there is no such thing as a Text file or a Binary file; if there were, there would be an Attribute bit for it, since there were at least two bits spare originally. A file is a file is a file. It consists of as many bytes/characters as the directory entry says. Some files are often best treated in a special manner by DOS, with an ^Z being a terminating character (maybe only if in the last sector or last 128 bytes). This is done to support an older convention (CP/M?) where the directory entry did not give the exact number of bytes and so a free-format file needed a terminating character/byte.This convention was used for files which were intended to be interpreted basically as lines of characters with newlines (of whatever form) where required. As this is generally useful, many quite independent programs support the text interpretation of a file, with or without ^Z.
