My first scan to find the start of the field is simple. But to get the end
of field, I will have to do multiple %scans for each of the 3 possible
characters (unless I am missing something). ...

I would use %XLATE to get a temporary with all the 3 possible end characters translated to the one of the end characters.

temp = %xlate(x'1d1e' : x'1c1c' : string);

And then use %SCAN on the temp string just looking for x'1c'. If you need to know what actual end character it was, you still have the original string.

Jon's idea to use %SPLIT sounds good too.
