Defining Arrays

This chapter contains procedures for defining, editing, renaming, and deleting an array. An array is a structure that stores sets of data within a function. The contents of an array are available only as long as the function is active. The structure has a defined layout and each entry (element) of the structure has the same layout. Define this layout with any set of fields from the model, such as attribute, code, and function fields.

Use arrays to:

Improve performance where a function requires repeated access and use of a finite number of entries, such as table lookups.
Move between a field and a data structure.
Sequence a finite set of data by a set of unrelated key fields.

Programmers (*PGMR) and designers (*DSNR) can define arrays.
