Function 37 which is the pre-set server function is no longer required on
current versions of software.

Function 38 is the split table function. This function allows the server to 
split products from a bill and create a new split bill  for the customer.
Once the products have been split it is then necessary for this part of

Function numbers from 41 through to 48 are not used.

The next function is code 49 which is the display open table report.
Upon depression of this key all the currently open tables will be
displayed on the screen. This will inform the Server of the table number,

The next function which is 51 is currency conversion. There are Up to 9
currency conversion rates that can be used. The amount due will appear
