The Pre-processor allows you to define up to 1000 data sets. The maximum number of items in all sets 1000000000; this apart, there is no limit on the number of items allowed in an individual set. Each item in a set may consist of up to 255 characters of text. You allocate a unique number or name to each set; this is known as the PP data set number. Data sets are defined using the *DATA command.

A set reference takes the form "AE.AE", where the first AE is the set number and the second the item number. References must be to already-defined items from already-defined data sets.

A set reference may also take the form "AE.#", where AE is the set number; the reference is evaluated as the number of items in the data set.

Examples of valid set references:

[dsMine.5]

[5.Loop]

[dsLots.#]
