Hello, i currently have the following immutable centerline: --------- immutable.th -------- survey immutable centerline -id zug_1 date 2014.11.15 team "Some One" notes team "Some Other" team "PersonWhoDidNot Attend" endcenterline input extensions.th endsurvey -------------------------------- The additional file "extensions.th" could be modified. I am able to add and change existing persons in the centerline, however i wonder how i can delete a person afterwards from the revise block: -------- extensions.th -------- revise zug_1 team "NewPerson added" # new team member -team "PersonWhoDidNot Attend" # team member i do want to delete: HOW DOES THIS WORK? endrevise ------------------------------- i hope such a possibility exists somehow, or if not, if someone skilled in C could add this please? With best regards, B. Hallinger
