From ibase.h:
#define blr_substring 40
Don't get too excited. It's not implemented, to the best of my

blr_substring is implemented - and actually used in some hand-coded
BLR used for rdb$trigger03 (don't sue me if I have the 03 part wrong...)

However, it is only correct for single-byte character sets.
