Reserved words (also called keywords) are symbols that have pre-defined and fixed meanings to the Irie Pascal compiler. The case of reserved words is usually not significant, so although the reserved words listed below are all in lowercase, by default the compiler will recognize reserved words regardless of the case of the letters. NOTE: There is a compiler option (-p) that will make reserved words and identifiers case-sensitive.

The reserved words recognized by the compiler are listed below (along with links to information describing how the reserved words are used):
