The majority of COBOL file operations performed by the Micro Focus File Handler operate in exactly the same way when performed by Xfh2btr on Btrieve files. However, due to underlying differences between the two systems, there are instances where behavior differs. These include:
- Keys
- Locked record detection
- OPEN OUTPUT operation
- Record lengths
- Current Record Pointer (CRP)
- Transaction processing
- WRITELOCK
Note:
Note:
You should especially note the positioning of the current record pointer (CRP) when performing sequential read operations after having written, rewritten or deleted records in a file.
