POSTPATH procedure in PH web screen

[Edis, Bob]

G'day all

I have a couple of questions regarding PH web screen syntax.  I have just
started creating/maintaining some of these screens and there is some syntax
issues I don't know about.  I would appreciate it if someone can clarify
these for me.

1. I notice none of the screens bother with SKIP, ALIGN or TITLE statements.
When I try to use the SKIP and ALIGN statements they do not have the desired
effect on the HTML page.  I.e. if I want the first row to have 2 fields and
the next to have 3, the HTML screen pushes the 3 field onto a new line as it
tries to put the fields into a table that has only 2 columns.

2. I am using existing screens as a template.  The coder has put a POSTPATH
procedure in the code that is not created by default.  E.g.

procedure postpath
begin
  if promptok for Vendor_Key of vendor         &
  and T_Flag <> "Y"
      then begin
             let T_Flag = "Y"
             defer linkscreen dw_vendor        &
                   action "loaddata"           &
                   passing Vendor_Key,         &
                           T_Flag
      end
end

Any ideas why and what this does?

TIA for your (polite) suggestions,
