In Algol-60, "while" was relegated to being one of the 3 forms
of for-list-elements, i.e.: a clause of its "for" statement.
The first appearance (that I can find) of a "while" statement 
as in Pascal was in Wirth's Algol-W [Wirth & Hoare: "A Contribution
to the Development of ALGOL", CACM, v. 9, n. 6 (June 1966)].
