I didn't follow right away, but now maybe I understand. It's the nature of
dialog boxes that the program state is different after using one. Sometimes
the state is unstable (perhaps there's a new working copy of a string which
needs to be validated and moved to the permanent string). Sometimes the
display needs to be changed (consider choosing different display sizes in a
page layout program). It's very tempting to assume that these functions will
only be needed after a redraw is requested at the end of a dialog. If FORMDIAL
suppresses that, and if those functions are folded into the redraw code,
confusion would result. The problem is one that becomes acute in multitasking:
anything may change under you without notice, at any time.
