[ic] Changing Global Catalog Variables Dynamically

[interchange-users@icdevgroup.org (Shawn Mathews)]

I have a client who wants to send transactions thru different gateways
depending on the type of card used and the credit limit associated with that
gateway.

I think to do this I need to change the value of MV_PAYMENT_MODE when the
transaction is being processed.

I figure to do it I would need to use:  $Global::Variable->{$key} or
something of the sort in a [perl][/perl] block.

Now, I may have hit the crack pipe once or twice this morning, so I want to
ask a few simple questions before I do something like this.....

#1) Am I crazy? Is this a really,really,really, dumb thing to do?
#2) Would it affect other transactions that were being processed?
#3) Would it be a better idea to put checks in Vend::Payment or write a
wrapper Payment module that sent the info off to the appropriate place?


Thanks,
