Hi Experts,

I am using a web service API to retrieve holiday information, please consider the following pseudo code:

Sub ButtonOnClick_ApiGetCountryList

     countryList = webService.GetCountryList

End Sub

Sub ButtonOnClick_ApiGetHotelList

     hotelList = webService.GetHotelList(Country)

End Sub

Sub ButtonOnClick_ApiGetAirportList

     airportlList = webService.GetAirportlList(Country)

End Sub

Sub ButtonOnClick_ApiGetBeachlList

     BeachList = webService.GetBeachlList(Country)

End Sub

Once the user has clicked the get country button and the web service has delivered a list of countries I need a country from that list to be available to the other three subs. How do I do this without using a global variable or is it OK to use a global variable?
