- - HISTORY -
-
- Version 2.10 - March 21, 1996
-
- - Added new function to registered DLL(rv). RexxBase_WriteDBFWithLock. This will allow serialization
- of database writes and prevent errors when multiple hits occur to the same database file and associated
- index and text files.
-
- - Added database variable "databasename".dbasefileformat. This returns dBase3 or dBase4, based on
- the dbf's format. Note: without MDX files or MEMO fields a DBF file format defaults to dBase3.
-
- - Added internal record locking to registered version (rv) through the use of semaphores.
-
- - DLL program would allow for only 3 MDX tags.
-
- - EXE program could not create indexes with numeric fields.
-
- -Recompiled INSTALL.EXE and REXXBASE.EXE with newest version of VisPro/REXX. (3.01).
-
- - Modify function was using the current file's dBaseFileFormat field instead of the global field. Thereby,
- preventing conversions of files from one format to another.
-
- -Added Drag and Drop to EXE main window. If you have a DBF with an OS/2 setting type of "DBF",
- then you can drag onto the EXE, while it's running, and have it added to the list.
-
- - Documentation failed to fully describe the RexxBase.ERROR control variable.
-
- -Corrected documentation with regards to specifying a TAG name when opening a file.
-
- -Writes followed immediately by an Update would not create valid indexes and caused SYS3175 errors.
-
- -Corrected EXE errors when catalog file contained a DBF that doesn't exist.
-
- -Corrected problem when adding an MDX tag in the EXE. The tag name would not show up.
-
- -PackDBF function didn't update the header correctly.
-
- Version 2.06 - January 22, 1996
-
- - Install program was marked as not executable.

-
- Version 2.04 Sept. 30, 1995
-
- - ReadPrevDBF and others failed when GOTORecord(bottom) was used.

- - UpdateDBF failed for both NDX and MDX indexes.
-
- - Packing dBase IV style DBT files used incorrect blocking factor. This could
- and most likely did create exception conditions.
