control structure



#group refers to the set of currently active groups. It is used to add new groups to the active groups rather than replace them: using group tom and dick and harry and #group.

For example, the following element rule makes use of #group to add the group "process-part-number" to the current active rule groups:

  element part-no
     using group #group and process-part-number
        output "%c"
