I am using a web service API to retrieve holiday information, please consider the following pseudo code:
countryList = webService.GetCountryList
hotelList = webService.GetHotelList(Country)
airportlList = webService.GetAirportlList(Country)
BeachList = webService.GetBeachlList(Country)
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?
