COMMALISTSA commalist is a list of items, usually delimited with commas. For example:Harry,Ron,Hermione Commalists allow a set of values to be manipulated as a unit, which is often convenient. There are conditional expression operators and functions that can process commalists. Commalists may be suitable when individual values are known to be small in size (such as integer id numbers) and where it is known that there will not be a large number of choices. The total length of a commalist is limited to 250 characters.
The separator character is comma by default. This cannot be "escaped" but it
may be changed to another character using the script directive
#control listsep
