I think Scott's file format is variable, with records delimited by newline. In this case, Scott, you can use %Stream.FileCharacter to read it if you set property LineTerminator = $C(10).

I have no experience with HL7 either.

Numeric operators convert their arguments to numbers (according to well defined rules) before performing the operation. That's why "5apples"+ "7 orange" gives 12.
Conversely, string operators convert their arguments to strings before the operations is performed.

In other words, regardless of the arguments, the operator automatically performs the necessary conversions according to what it expects.
