Course Overview

What this Pascal course covers, how to use it, prerequisites.

A self-contained, hands-on course covering the Pascal programming language and its modern descendant Object Pascal, as implemented by Free Pascal (with the Lazarus IDE) and Embarcadero Delphi: history and dialects, tooling, program structure, data types, control flow, procedures and functions, arrays, records, sets, strings, pointers and dynamic data structures, files and streams, units, exceptions, compiler directives, classes and objects, properties, inheritance and polymorphism, interfaces, generics, anonymous methods, operator overloading, helpers, enumerators, RTTI and attributes, memory management, multithreading, C interoperability and inline assembly, GUI development (LCL, VCL, FMX), databases, networking, JSON/XML, cross-platform compilation, package managers, unit testing, debugging, and complete projects. Every chapter has compilable examples, and every part ends with exercises.
