- Fixed some bugs I created when I cleaned up, thanks Christof.
Wed Mar 1 10:49:03 CET 2000
- Synced preproc.y with gram.y.
- Added output of arrays.
- Set library version to 3.1.0.
- Set ecpg version to 2.7.0.

......@@ -16,8 +16,6 @@ the parser.
it would be nice to be able to use :var[:index] or :var[<integer>] as
cvariable for an array var
How can one insert arrays from c variables?
What happens to the output variable during read if there was an
indicator-error?
......@@ -26,10 +24,7 @@ Add a semantic check level, e.g. check if a table really exists.
It would be nice if there was a alternative library using SPI functions
instead of libpq so we can write backend functions using ecpg.
make ECPGnumeric_lvalue more accurate by using something like ECPGdump_a_*
remove space_or_nl and line_end from pgc.l
Missing statements:
- exec sql ifdef
- SQLSTATE
