Rather than type in parameter assignments one at a time, it is possible to invoke a text editor (EDT in VMS, vi or the editor given by the EDITOR environment variable in UNIX) to edit the taskname.def file. As usual, if no taskname is given, view will edit the taskname.def file indicated by the taskname% prompt. If a taskname is specified, e.g.:
histo% view itemizethe existing file itemize.def is edited, and the selected task is changed to itemize. Note that if the itemize.def file did not exists, one is created.
