2.2.3 Arrays

Frequently, the programmer will want to refer to a group of data by one name and still be able to refer individually to elements in the group as necessary. Such a group is called an array.

An array name is the symbolic name assigned the array when it is defined in a DIMENSION statement, type statement, or COMMON statement (Chapter 3). An array element is one member in the group of data. An array element name is an ar~ ray name qualified by a subscript enclosed in parentheses.

The following table could be produced by rewriting the program in Figure 1~1 to generate four 1~dimensional arrays. The table lists three players, times at bat, hits, and batting averages. Thus the array definitions for these four arrays could be PNAME(3), AB(3), HITS(3), and A VG(3).

PNAME AB HITS AVG

GEHRIG 49 14 .286

OTT60 21 .350

RUTH54 18 .333

We can refer to any element in these arrays by using a subscript. For example, the hits for 'OTT' can be referenced as HITS(2) and the batting average for RUTH as AVG(3).
