Line 2,221:

* {{note|step|a}} "<code>step</code> n" is used to change the loop interval. If "<code>step</code>" is omitted, then the loop interval is 1.

* {{note|Ada_quantifiers|b}} This implements the [[universal quantifier]] ("for all" or "<{{math>\|&forall</math>";}}) as well as the [[existential quantifier]] ("there exists" or "<{{math>\exists</math>"|&exist;}}).

* {{note|COBOL THRU|c}} <code>THRU</code> may be used instead of <code>THROUGH</code>.

* {{note|COBOL GREATER THAN|d}} <{{code>|2=cobolfree|«IS» GREATER «THAN»</code>}} may be used instead of <code>></code>.

* {{note|Rust FOREACH|e}} Type of set expression must implement trait <code>std::iter::IntoIterator</code>.
