HELP SECTION
DOTV
Type: Adverb (Logical, > 0 => true)
Use: If true, use of the TV is requested. Additional meaning is
attached to values > 1 by some tasks. For example. XGAUS and
friends use the TV for menus when DOTV is 2 and the terminal when
DOTV is 1. IMAGR chooses the initial facet to display by DOTV.
