this is possible. There are two ways to achieve it:
obtain the most recently entered value "Order type".
V[ortype] "&[::Order type]"
"link" command in GuiXT script of the screen that contains the entry
V[VA01_ortype] F[Order type]
solution (b) for the following reason: If there is another entry field
"Order type" in one of the VA01 screens that you process later on, its
value will overwrite the value &[::Order type], and not your own variable
