In 1957, [[Charles Leonard Hamblin]] invented the programming language '''GEORGE'''.<ref>

It was designed around a push-down pop-up stack for arithmetic operations, and employed reverse Polish notation.

The language included loops, subroutines, conditionals, vectors, and matrices.

Line 33:

Manipulation of vectors and matrices requires subscript notation. In GEORGE, the subscript(s) preceded the vector or matrix name. Thus A(j) was written j | A.

The following program reads in vector <i>''a</i>'' of 10 values, then forms the squares of those values, and finally prints those values.
