Macro Language Elements
The section contains detailed specifications for all 1010data Macro Language elements.
- Data Transformation
  Data transformation operations use functions and expressions to functionally alter tabular data. These operations take 0, 1, or 2 tables as input and produce a single table as a result.
- Blocks
  Blocks allow users to reuse sections of Macro Language code and to parameterize values in that code for greater flexibility and power.
- Application Development
  - <dynamic>
    The <dynamic> element creates an environment in 1010data that maintains the state of system interactions and controls the running of queries.
  - <render>
    The <render> element provides the ability to configure certain QuickApp widgets when rendered to available output targets. A single <render> element contains one or more elements that specify output targets and settings for the final output.
  - <layout>
    The <layout> element is a nestable pseudo-operation that can be used to organize <widget> elements and other <layout> elements.
  - <widget>
    <widget> is used to define all visual components of a QuickApp, including drop-downs, text boxes, tables, and calendars. The form a widget takes is controlled by the class_ attribute.
  - <do>
    A <do> clause within a <dynamic> provides the ability for <dynamic> variables to be updated when some variable within the scope of the <dynamic> is changed.
