Re: Pricing Routines to perform Unit Price conversions before used in sub/totaling

[Barry Treahy <treahy@mmaz.com>]

******    message to minivend-users from Barry Treahy <treahy@mmaz.com>     ******

The problem is that it isn't a standard conversion... In the case of US$ to UK pount, the unit price is $p *
1.12 / 1.6 * 70.00 and I haven't found a method or example of MV handling that.
