Once I Have Used The Netware Btrieve Nlm V6.10x Can I Switch Back To Btrieve For Dos, Btrieve For Os/2, Or Btrieve For Windows? |

Answer» If your system requires that the files be available for both NLM and client use, there are several steps to take to insure the proper use of the file: Do not convert the 5.x files to the 6.x FORMAT. The versions of Btrieve for DOS, MS Windows, and OS/2 do not support the v6.x file format. Read the SECTION of the Btrieve v6.10 README file that gives instructions on preimage files. Btrieve v5.x and v6.x pre-image files are incompatible and you need to take steps to prevent the different versions of the engines from using different version of the pre-image file. When using BSETUP, be sure to select the option that creates files in the 5.x format. If this option is not used all files that are created will be in the new 6.x format and the clients will return status 2S when trying to access them. If BTRIEVE.NLM v6.1x is configured with the -d option to force Btrieve to create files in v5.x format, what would happen if v6.1x file flags like: Index Balanced File Duplicate Pointers Key Number Specified VATs used in File are set at creation time? These bits are IGNORED if you load NETWARE Btrieve v6.1x with -d. No errors will be returned. For more information about these new file creation options, see the Btrieve Programmer's Manual included with the Btrieve Developer's Kit Supplement.
