Mad-Pascal (MP) is a 32-bit Turbo Pascal compiler for Atari XE/XL. By design, it is compatible with the Free Pascal Compilator (FPC) (the -MDelphi switch should be active), which means the possibility of obtaining executable code for XE/XL, PC and every other platform for which FPC exists.

MP is not a port of FPC; it has been written based on of SUB-Pascal (2009), XD-Pascal (2010), the author of which is Vasiliy Tereshkov.

A program that works on Atari might have problems on PC if, for example, the pointers have not been initialized with the address of a variable and the program attempts to write to the address $0000 (memory protection fault).

The strengths of MP include fast and convenient possibility of inclusion of inline assembly. A program using inline ASM does not work on platforms other than 6502 CPU. MP uses 64KB of primary memory; TMemoryStream provides usage of extended memory.

Variable allocation is static; there is no dynamic memory management. Parameters are passed to functions by value, variable or constant.

The available features are:

• If Case For To For In While Repeat statements
• Compound statements
• Label Goto statements
• Arithmetic and boolean operators
• Procedures and functions with up to 8 parameters. Returned value of a function is assigned to a predefined RESULT variable
• Static local variables
• Primitive data types, all types except the ShortReal, Real type are compatible. Pointers are dereferenced as pointers to Word:
  • Cardinal Word Byte Boolean
  • Integer SmallInt ShortInt
  • Char String PChar
  • Pointer File Text
  • ShortReal Real fixed-point
  • Float16
  • Single / Float
• One-dimensional and Two-dimensional arrays (with zero lower bound) of any primitive type. Arrays are treated as pointers to their origins (like in C) and can be passed to subroutines as parameters
• Predefined type String [N] which is equivalent to array [0..N] of Char
• Type aliases
• Records
• Objects
• Separate program modules
• Recursion

This is a text mode windowing library complete with window controls and modern gadgets (widgets). The gadgets allow you to build input forms that use buttons, radio buttons, input strings (with scrolled lengths and type restrictions), check boxes, progress bars, etc. This allows you to build applications with "modern"-ish interfaces.
