5.3.10. List of Sections
Purpose:
Select the list of sections according to the given
constraints and current environmental parameters. The Publication,
Language, Issue, Section parameters may not be defined outside List
Section statement; inside the statement however, all these parameters
are defined. The code between "List .. Article.. " statement and
"ForEmptyList" (if used) or "EndList" is repeated for every article in
the list. When the list of article is empty the code in between
"ForEmptyList" and "EndList" is executed once.
Syntax:
List [length <integer_value>] [columns <integer_value>]
Section
[<list_of_section_constraints>] <list_of_instructions>
[ForEmptyList [<list_of_instructions>]]
EndList [Section]
where
length <integer_value> where <integer_value> specifies list_length forces the list to have at most list_length items. If the list contains more items than list_length items the ones not fitting in can be listed using If NextItems/PreviousItems statements.
columns <integer_value> where <integer_value> specifies columns_number
sets an environment variable. This is incremented as if the items would
be placed in a table cell. The counting starts from one and the
variable is incremented for every new element. When it reaches the
maximum value it is reset to one. This is very useful in building tables of data. For details see If List.
<list_of_instructions> may contain any statement except: "Language", "Publication", "List Issue", "Issue", "List Section", "Section".
| <list_of_section_constraints>= | [<section_constraint>] <list_of_section_constraints>
| <section_constraint> |
Any parameter used in <list_of_section_constraints> can only be used once.
Inside
List Section, the data context is defined by the constraints applied to
the current section for every processed line. The data context is
restored after the list processing.
Constraints:
Inside List Section the following statements are forbidden:
Language
Publication
List Issue
Issue
List Section
Section
List Section statement cannot be used inside List Article, List Subtitle, List SearchResult statements.
