16.5: Internal Functions and Subroutines

All of ANA's built-in functions and subroutines are described below. Functions are followed by the list of comma-separated arguments, if any, between parentheses. Subroutines are followed by the comma-separated list of arguments, if any, separated from the subroutine name by a comma. Arguments between square brackets are optional. Arguments followed by three dots may be repeated zero or more times. Generally, the user may specify any number of the optional arguments, provided no unspecified argument precedes any specified argument between the same square brackets.

Arguments that are indicated in one of the following two manners are keyword arguments: /KEYWORD or KEYWORD=value. These arguments may be specified in any order and in any position, and their placement does not influence the interpretation of non-keyword arguments.
