Standard Pascal (i.e. ISO/IEC 7185) allows implementations to include extensions to Pascal. An extension is not allowed to invalidate any program that would be valid without the extension, except those programs that are invalidated only because of new keywords added by the extension.

Irie Pascal supports a number of extensions to Standard Pascal. Some of these extensions were added for compatibility with Turbo Pascal or Extended Pascal, while others are specific to Irie Pascal.

Support for extensions can be enabled and disabled using the Extensions Project Options page (see the Irie Pascal User's Manual for more information).

The Irie Pascal extensions are listed below:

• Allow relaxed declarations
• Allow constant ranges
• Allow 'otherwise'
• Allow relaxed parameter list congruity
• Allow non-numeric statement labels
• Allow underscores in identifiers
• Allow binary and hexadecimal integers
• Auto-declare Input and Output
• Allow double-quoted literals
• Enable non-standard operators
• Enable non-standard constants
• Enable non-standard types
• Enable non-standard variables
• Enable non-standard functions
• Enable non-standard procedures
