how could I count the number of commas in a string variable containing
words separated by commas? I remember similar question in this list but
sorry I could not find it. by the way, maybe it's my school's sever problem
but I did not receive any emails from the list between 5:30PM till 11:50PM
on Thursday, including the same message I sent to the list. Same thing
happened yesterday. just curious. Thank you.
cheers,
Wanli Zhao
