- added RELEASE_REQUESTS FOR <dbname> as an embedded SQL command as well as QLI
- changed the RM/Cobol code generator to use isc_compile_request rather than isc_compile_request2
- changed the RM/Cobol code generator to use isc_dsql_allocate_statement rather than isc_dsql_alloc_statement2
As a result of this change RM/Cobol programs will have clean up their handles by issuing a RELEASE_REQUESTS call before exiting a subprogram using the EXIT PROGRAM verb.
This batch of changes includes:
- Support for FIRST/SKIP clauses
- Support for CURRENT_CONNECTION, CURRENT_ROLE, CURRENT_TRANSACTION and CURRENT_USER context variables
- Changed the BLR generated for RM/Cobol programs to use blr_cstring
rather than blr_text so that CHAR and VARCHAR fields are not written
as "fixed length" fields from Cobol programs. Incoming CHAR and
VARCHAR fields are right filled with spaces inbound to the Cobol
program and stripped of trailing spaces outbound.
