Using VPLUS: An Introduction to Forms Design (32209-90004)

1-3
Block Mode
FORMSPEC operates in block mode. In block mode, all data typed in
unprotected areas on the screen is sent to FORMSPEC at one time when you
press ENTER, rather than line-by-line as with RETURN. FORMSPEC issues
"menu" screens on which you type any necessary information into
"unprotected" areas of the screen. (Unprotected areas are highlighted.)
You move to the start of each successive field by pressing TAB. The next
sections, in which you design increasingly complex forms, describe in
detail the information you enter on the FORMSPEC menus.
FORMSPEC Function Keys
Before running FORMSPEC, you should understand how your terminal func-
tion
keys are used for FORMSPEC. The functions executed when you press these
keys coorespond to the labels displayed on the terminal screen by
FORMSPEC, as shown in Figure 1-2.
