Gary,
The original author of the tpsHL7CompareField proc (yours truly) did not code some of the features very wisely. In all of the versions I have seen posted on the forum, a LIST argument must contain at least 1 value to be considered valid.
Later versions of the proc contained a REGEXP option. This would allow a Regular Expression to check for “1 or more” characters in a field. Unfortunately, changes to our corporate policy make it more difficult to submit code to Clovertech. Please e-mail me directly if you are interested in fixing the code.
