Array Functions

Arrays are a powerful and extremely useful programming concept. If you've done any programming in languages such as C++, Perl, PHP, or Visual Basic, you're probably very familiar with both the concept of arrays and some uses for them. We think it likely, however, that most FileMaker Pro developers out there haven't had much experience with arrays and will benefit from both a formal and practical discussion of them.

Abstractly, an array is essentially a structure that can hold multiple values. The values are ordered within the structure and can be referenced by their position or index number. Figure 14.17 shows a representation of a simple array. The array has been defined to hold up to seven values, but only four values are present. The first element in the array is the value “red.”
