There are numerous different compilers you can use. In this article, Mytour will provide you with some suggestions for selecting a Pascal compiler.
A compiler is a program specialized in processing commands written in a specific programming language into machine language or code that the computer's processor uses.
Below are some suggestions for selecting a Pascal compiler.
Online Pascal Compiler
Users can set up an online Pascal programming environment to compile and execute all available examples online. The online Pascal compiler helps users feel more confident with what they are reading and allows users to verify programs with different options, modify any example, and execute them online.
Below is an example using the online Pascal compiler available on CodingGround:
program HelloWorld;
include crt;
(* This marks the beginning of the main program block *)
start
writeln('Hello, World!');
presskey;
finish.
In most examples provided in this guide, you will find a 'Try' option in the code sections on the website's top right corner to access the online Pascal compiler.
Some available Pascal compiler programs include:
- Turbo Pascal: offers an IDE and compiler to run Pascal programs on CP/M, CP/M-86, DOS, Windows, and Macintosh.
- Delphi: provides compilers to run Object Pascal and generate open-source code for Windows 32-bit and 64-bit, as well as Mac 32-bit, Mac OS X, and iOS. Embarcadero plans to support Linux and Android operating systems.
- Free Pascal: a free compiler to execute Pascal and Object Pascal programs. Free Pascal compiler includes both Turbo Pascal and Delphi, compatible with both 32-bit and 64-bit versions on Linux, Windows, OS/2, FreeBSD, Mac OS X, DOS, and some other platforms.
- Turbo51: a free Pascal compiler for the 8051 microcontroller line, using Turbo Pascal 7 syntax.
- Oxygene: this is an Object Pascal compiler for .NET and Mono platforms.
- GNU Pascal (GPC): a Pascal compiler including a front end for the GNU Compiler Collection.
In the following guide, Mytour will instruct you on how to install and use Free Pascal.
You can download the Free Pascal compiler here and install it on your computer: Download Free Pascal
Installing Free Pascal on Linux
On Linux distributions, Free Pascal comes in three forms:
- A tar.gz version, also available as separate files.
- An .rpm version (Red Hat Package Manager).
- A .deb version (Debian).
Installation code for the .rpm version:
rpm -i fpc-X.Y.Z-N.ARCH.rpm
Where X.Y.Z is the version number of the .rpm file and ARCH is one of the supported architectures (i386, x86_64, ...).
Installation code for Debian version (such as Ubuntu):
dpkg -i fpc-XXX.deb
Where XXX is the version number of the .deb file.
Installing Free Pascal on Mac
If you're using Mac OS X, the simplest way to use Free Pascal is to download the Apple Xcode development environment and follow the installation instructions. Once Xcode is set up, you can comfortably use the Free Pascal compiler.
Installing Free Pascal on Windows
For Windows operating system, you will need to download the Windows installer, setup.exe. This is a typical installation program. Then follow the steps below to install Free Pascal:
- Choose a directory.
- Select the components of the package you want to install.
- You can choose to associate .pp or .pas extensions with the Free Pascal IDE.
Text Editor
A text editor is used to input programs. Some prominent text editors include Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, Vim, or Vi.
The name and version of text editors vary slightly across different operating systems. For instance, Notepad is commonly used on Windows, while Vim or Vi may be utilized on both Windows and Linux or UNIX.
Files created using a text editor and utilized for coding are referred to as source files, containing the program's code. Source files for Pascal programs are typically named with the .pas extension.
Before diving into programming, ensure you have installed a text editor and, of course, gained enough experience to write a computer program. Save this program in a file, compile, and finally execute it.
Here, Mytour has just provided you with some suggestions for selecting a Pascal compiler. Additionally, you can explore the top 3 best Code editors on Mac and Linux to choose the most suitable code editor for your programming tasks. Are you new to programming, and which Pascal compiler are you using? Share your thoughts with Mytour.
