Epi Info™ User Guide
How To: Use Check Code
Epi Info™ allows the creator of the questionnaire or survey to guide the data entry process to produce range checking, automatic skip patterns and coding of variables. This is accomplished using Check Code. Many other more complex functions are possible such as mathematical or logical operations, checking the value of a field against the value of one or more other fields, and displaying helpful dialogs or custom error messages. Click the Check Code button to open the Check Code Editor. For information about the Check Code Editor, refer to the Check Code section of the user guide.
