WksCodeMatch ​
Determines the number of characters of the workshop code to use in time slot/workshop group matching on the Enrollment Cart page. For a given course, workshops will be considered to reside in the same time slot/group if the first N characters of their codes match.
For example, if WksCodeMatch is set to 2, all workshops that start with AA will be in the same time slot/workshop group. And web users will only be able to select one workshop per time slot/group when enrolling in the course.
If set to 0 (zero), no enrollment restrictions will be applied.
For more workshop selection options, see the oCourse.HTMLWkshoplist function.
