selector

The selector matching code was primarily developed for the choise of orders and its printouts, but it in the meantime is has also been used within other contexts.
The presenting of all orders containing the status of the present desired process (e.g. the printing of order confirmation) is common. Mostly the order number and the customer's short name are presented. The sorting out of the lines via pressing a button between the two kinds of contents can be switched, so that e.g. one can print out all ABs for one customer. The process (usually printouts) are done in the choosen order.
The switching board from left to right:

· using (printing) the selected lines (all selected lines are seen on a dark background)
· choosing all presented lines
· getting rid of all selected lines
· Change of sorting (typically between customer's short name and order number)
·Forms define a primary printer ("Drucker") which is presented at this point and is variable.
