I'm migrating an application from mapping1 to mapping2 of MSS.
Both "Numeric I3" and "Numeric I4" seem to map to integer, although Uniface accepts "larger" integer numbers in I4 (perhaps 3 or 4 bytes).
If you have used "Numeric C5" in mapping1, is there any loss by always using "Numeric I4 LEN(0-5)", although "Numeric I3 LEN(0-5)" would be enough?
Or in other words, what's the practical difference between I3 and I4?
