Comma-delimited lists

A comma-delimited list (or "list" for short) is a list of items, delimited with commas. A list is stored as a single alphanumeric variable or field. Individual members cannot contain embedded commas. Embedded whitespace is allowed within or outside of individual list members (the list may need to be quoted).

An example: Harry,Ron,Hermione

Lists are most suitable where individual values are known to be small in size (such as controlled-vocabulary tags or integer id numbers) and where it is known that there will not be a huge number of choices. The total length of a comma-delimited list is limited to 250 characters.

Lists allow a set of values to be manipulated as a unit, which is often convenient. They can be used within conditional expression operators such as IN, INRANGE, and CONTAINS. Some functions also work with lists.
