Pick Item YY qty N

Scan barcode:

Enter Qty Picked:

Of course you can see how you might handle incorrect items or wrong quantities by having your application generate prompts such as

Incorrect Item

Scan correct item:

Too many items

Pick item YY qty N

Enter Qty picked:

These are just examples and there are other ways to design a transaction of this sort. The point is that you will need to create a data structure that

defines the transaction and another data structure that keeps track of where in the transaction each terminal is (state management), independent of any

other terminals that might be active.

You will need to create a data structure or record of some sort that keeps track of each terminal's state. The structure might keep track of where in a transaction process a terminal is; any pending data from, or prompt for, the terminal; and any other information that is relevant to a terminal in the transaction process you have defined.

An easy way to create a data structure for each terminal is to define an array of User Defined Type (VB) or Records (Delphi) or Structs (C++). The array would be large enough to accommodate all of your terminals (one array element for each terminal) and might look something like this in VB

Type TermData

TermID as integer

TransactionIndex as integer

PendingPrompt as string

PendingData as string

ErrorCode as integer

Transaction as TransactionData

Etc.

End Type

dim Terminals(25) as TermData

You will also need to define a transaction. Typically the transaction is applied to all terminals so it is a single structure (there is not a copy for each terminal)

Type TransactionElement commandcode as integer promptline1 as string
