Data structures

Describes how the basic data types can be combined using arrays, tuples, and sets to obtain complex data structures.

Ranges
Integer ranges are fundamental in OPL, since they are often used in arrays and variable declarations, as well as in aggregate operators, queries, and quantifiers.
Arrays
Describes one-dimensional arrays and multidimensional arrays.
Tuples
Data structures in OPL can be constructed using tuples that cluster together closely related data. This topic describes how to declare tuples, use keys on tuples, and initialize tuples.
Limitations on tuples
When using tuples in your models, you should be aware of various limitations.
Sets
Gives a definition of sets, a list of the operations allowed on sets, and a few words on their initialization.
Sorted and ordered sets
Shows the effect of the sorted property on simple sets, tuple sets, and sets used in piecewise linear functions.
