I was so stupid when you first pointed out that I should add a line to empty str1 with str1[0]=0; but I thought you had typos so that I simply added the single quotes: str1[0]='0'; Last night I actually tried str1[0]='\0'; without realizing that is the right way, or understanding until your last reply. It finally works now and I understand it better.
Thank you so much for all your time and patience with me!
