Abstract
With this section we conclude the study of all the FORTRAN statements necessary to perform calculations like those programmed in Figure 1–5. (We still have not studied output statements such as on lines 15,16,17,31 and 32. But the simplified output instructions at the end of Section 2 enable us to output the essential results.) Here we discuss two ways in which functions occur in FORTRAN programs. In the first, the programmer uses a function whose definition is supplied as part of the software. FLOAT and IFIX (Section 2) are examples of such supplied functions. We discuss others below. In the second, the programmer writes a definition of the function into his program as on line 7 of Figure 1–5.
