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.
