Syntax

Syntax of ParaPascal

ParaPascal is based on standard Pascal programming language.
Not all pascal constructs are implemented at the moment.
Unlike standard Pascal, ParaPascal is case-sensitive, keywords are lowercase.

Implemented Features

• Standard output: write/writeln
• All Code Sections: const, type, var
• All Operators: + - * / div mod ~ & | ! not and or xor ...
• Statements: if, for, while, repeat
• Functions and Procedures
• Parameters by name and by reference
• Basic Types: integer, real, boolean
• Interval Type (integer only)
• Arrays (multi-dimensional)
• Records
• Nesting of Arrays and Records

---

Not Implemented Features

• Standard input: read/readln
• Nesting of functions and procedures
• Name overloading
• Statements: case and with
• Basic Types: string and character (string constants are supported)
• Enums and Sets

Small Differences (will be removed in the future)

Type real has 4 bytes while in standard pascal it has 6.
Nested arrays cannot be defined using shorthand notation.

Concurrency Features

• Concurrent block: cobegin/coend
• Concurrent loop: cofor
• Shared Variables: shared
• Semaphores: init, wait, signal
• Conditional Critical Regions: region, await

Roadmap

ParaPascal's aim is full compatibility with standard pascal and support for Monitors.
