Hi,   Im looking at an old code that uses that seemingly uses the # number sign symbol but I cannot figure out what its function is and it does not seem to exist on the internet.   For example, A = X#Y is something close to what I am seeing.   Could be be an old language/syntax that is no longer being used? I am relatively new to SAS and not familar if there was even an old syntax.   I really need to know as soon as possible, THANKS ... View more
