scanner {   
  Exec("printf "1\n2\n3"") {  
    Fst = Grab(First)
    Lst = Grab(Last)
  }

Line number will come in handy
I have to invent ugly designs

Exec("echo '#1# #2# #3#'") {
    Hlp  = Regex("#([^#]*)#") #1
    Hlp1 = Regex("#[^#]*#\\s*#([^#]*)#") #2
    Hlp3 = Regex("\"[^\"]*\"\\s*\"[^\"]*\"\\s*\"([^\"]*)\"") #3
    Hlp4 = Regex("\"[^\"]*\"\\s*\"[^\"]*\"\\s*\"[^\"]*\"\\s*\"([^\"]*)\"") #4
}
