Syntax:
variable-name = new result-type index-type-list
The index-type-list is a list of one or more type names expressed in either of two syntaxes (or a mix of both, if the mood suits you):
[ type-name, type-name, type-name ]
or
[ type-name ][ type-name ][ type-name ]
Description:
The array creation statement creates a new empty array. The array has a result type, and one or more index types. Valid types are: String, Integer, Float, Date, DateTime, Time, DateDiff and Boolean. Note that any of these types may be used as an index type. In many languages this would be called a map, dictionary or sparse array. The firstIndex() and lastIndex() functions, as well as the for/in loop, retrieve the values from the array based on the sorted order of the index values, not based on the order they were added.
Example:
For the following short program:
usHistory = new String[Date];
usHistory[toDate("12/15/1791")] = "Bill of Rights Ratified";
usHistory[toDate("07/04/1776")] = "Independence Day";
usHistory[toDate("06/21/1788")] = "U.S. Constitution is Ratified";
usHistory[toDate("10/19/1781")] = "U.S. Wins Revolutionary War";
outStr = "";
for (date in usHistory) {
outStr += date + " - " + usHistory[date] + "\n";
}
Alternatively, the last three lines could be written with the more advanced looping syntax like so:
for (date, event in usHistory) {
outStr += date + " - " + event + "\n";
}
With either looping syntax result in outStr would be:
07/04/1776 - Independence Day
10/19/1781 - U.S. Wins Revolutionary War
06/21/1788 - U.S. Constitution is Ratified
12/15/1791 - Bill of Rights Ratified
