I agree with Martijn on all the things he wrote.

Or, perhaps steal one bit from the RDB$PARAMETER_TYPE field and use it
to flag this. Currently it only has values 0 and 1. Perhaps it could be
extended:

0 - input
1 - output
2 - input + TYPE OF used
3 - output + TYPE OF used


Why is this better than adding another field? Well, it would allow tool
makers to write a single SELECT for the DDL extraction and have to first
detect version of Firebird.
