SuccessWare Index Driver (SIx Driver) Maintenance Update
June 24, 1992
The enclosed programs (SIX-UPD.EXE and NG-UPD.EXE) will update your
DBFSIX.LIB and DBFSIX.NG, respectively, to the 2am version from either the
original midnight release or the 1am version.
Problems fixed in the 1am version:
* Intermittent problems encountered when a VM swap occurs during an update
(before record pointer is moved or dbCommit() executed). Index
incorrectly updated.
* Temporary delay on PgDn in browse when last record in index falls within
SCOPE range (set with SET SCOPETOP/SET SCOPEBOTTOM, sx_SetScope()).
* Small difference in handling of SOFTSEEK.
Additional fixes/changes in the 2am version
* Algorithm changed for handling GO BOTTOM within a SCOPE. Much improved.
* If record pointer was on a record outside of the SCOPE, SKIP did not move
record pointer back into SCOPE. Corrected.
* FoxPro stores aliased fields in index expressions using a period (.) to
separate the database and field (TABLE.FIELD) instead of the standard
arrow (->) used by Clipper (TABLE->FIELD). This caused an argument
error opening indexes created or modified by FoxPro that contained
aliased fields. This is now correctly translated.
* SEEKS on a character value longer than the index key length failed. SEEK
values are now trimmed to key length.
* Doing an APPEND FROM with a source database that has a structural .CDX
containing tags with aliased fields in the key expressions caused an
"Alias Not Found" error, due to that fact that the alias is not added
to the symbol table when the database is opened this way. The
structural .CDX is no longer opened when a database is opened for an
APPEND FROM.
* The Norton Guide (DBFSIX.NG) is now Norton Guide compatible! <g>
