I was wondering if there was any way to convert input from a string variable so that lowercase letters would become upper case. For example if the input is ao89765 it would be converted to AO89765. My data(a huge amount of it) is all uppercase and the search doeasn't work if the input variable contains lower case letters. Being able to convert it would save me from having double the data I have now. I use Qbasic 7.1 if that means anything. Thanks for your help.
