ANA
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.
