The WEB variable enables you to define an HTML reference for each activity. This HTML reference is currently associated with all the schedule bars, milestones, and ID variables that correspond to the activity. The WEB variable is a character variable, and the values need to be of the form "HREF=htmlpage."

In addition, you can also store the coordinate and link information defined by the WEB= option in a SAS data set by specifying the IMAGEMAP= option in the PROC GANTT statement. By processing this SAS data set using a DATA step, you can generate customized HTML pages for your Gantt chart.
