Numeric column in a dataset has "C" as a value

[rtaylor]

A variable in a dataset is of type numeric, but shows a value 'C' when viewed or printed. Format is best12.

SAS Output:

			10
			21
			27
			12
			C
			10
			16

What does it mean? Is it missing? How do I exclude such values?

Its a special missing, you may find this paper helpfull:

And you can use the missing() function:

Or check specifically for that.
