In the Eiffel language, there are certain words that are considered "reserved". These words have specific meanings recognized by the compiler. As such, it is invalid to attempt to use a reserved word as an ordinary language identifier.
|
|
|
|
The reserved words listed in the ISO/ECMA standard are show below with a brief explanation of their meanings.
