Naming user-defined variables

Procedure

Define the variables in the Context view in the Talend Studio workspace following the pattern parameter_<parameter_name>, all in lower case, where:
- parameter_ is the fixed prefix.
  If you do not use the parameter_ prefix, the parameter will appear in the Advanced parameters section of the task creation wizard instead of the Parameters section after the artifact is published to Talend Management Console. The use of this prefix is not compulsory, it just changes the placement of the parameters in the app.
- <parameter_name> is the name of the parameter.
  Use underscore to separate words in the parameter name if necessary.
When you publish the artifact with the user-defined parameters to the Cloud, parameters fields are displayed and labeled with the parameter names you defined in Talend Studio, allowing the web user to set/change parameter values at runtime.
For further information, see Setting user-defined parameters.

For examples of context parameters, import the Talend Cloud Demos project to Talend Studio.
