lForms (LONG) - input
If 0, the number of forms codes defined is returned. If greater than zero, this function returns the number of forms codes for which information is returned.
For example, if there are five forms codes defined, and lStartForm = 2 and lForms = 3, a query is performed for forms codes 2, 3, and 4. The result is returned in the buffer pointed to by phciHcInfo.
