What's New in Tango Meta Tags
There are many new meta tags in this
version of Tango. They fit into all categories of functionality: URL,
form and CGI values, numeric operations, conditionals, database
output, data source information, date and time, user variables, string
operations, and array. As well, increased functionality has been given
to meta tags that existed in previous versions of Tango. The following
are a few of the upgrades and new inclusions to Tango meta tags.
- <@CALC> was a simple
addition, subtraction, division and multiplication calculator in
previous versions of Tango. In Tango 3.0, <@CALC>
has a new breadth of functionality: it can calculate and resolve
complex comparisons, mathematical operations, and logical processes.
- <@COLUMN> is now
recognized by Tango Server, whereas in previous versions it could
only be used in Tango Editor and was converted to <@COL>
automatically. This change means that you may now use <@COLUMN>
tags in files included with <@INCLUDE>.
- <@FORMAT> and the FORMAT
attribute permit you to control how values returned by Tango are
formatted.
- The <@ARRAY> tag lets you
create two-dimensional arrays for storage in variables.
- There are many new meta tags for working
with text strings, including tags for extracting substrings, and
finding and replacing text in a value.
- Date and time operations are now easier
with the addition of tags for adding and subtracting days to a date,
converting date and time values to seconds and back, and testing the
validity of date and time string values.
