Why is there no graphical user interface to the DCWatDes.Bitcode.* functions?

The provided AVENUE functions are more flexible this way. Bit codes can be useful for quite a number of operations. Try using the functions with the field calculator and the query. Examples are given in the section called “API Documentation”.

What is the Setup Dialog for?

The Extension depends on several software packages. The Setup Dialog allows you to use other versions of these software packages than the ones supplied with the Extension itself.

I get strange errors when I try to create the EPANET model. What can I do?

	Important

      THEN PUMP 355 STATUS IS CLOSED
