The Immediate Statement

The first ICL statement we will introduce is the immediate statement. This is used to make ICL do simple calculations. It simply consists of an equals sign (=) followed by an expression, and causes the value of the expression to be printed on the terminal.

    ICL> = 1 + 2 + 3
             6
    ICL> = SQRT(2)
    1.414214
    ICL>

ICL arithmetic expressions are very similar to expressions in FORTRAN, and will be discussed in more detail later.
