Work with Database Files Utility
The Toolkit utility Work with Database File utility (YWRKF) enables you to display and change the data on any database file - interactively. It includes the following features:
- Ability to change, add, delete, or copy records.
- Ability to work on single or multi-format files: formats may also be selected within a multi-format logical file.
- Positioning functions
- If the file has a keyed access path, the display may be repositioned using the key fields.
- If the file has an arrival sequence access path, the display may be repositioned using the relative record number.
- Ability to specify select/omit criteria, using a separate display
- A two level display:
- A record level display which enables you to scan through records quickly, and to compare records. Fields may be dropped from the record level display.
- A field level display that enables you to examine all the fields for a record.
- Alternate field labels - You may specify that fields are to be described either with their DDS field names or their DDS column heading text.
- File, format, and field descriptions.
- Hexadecimal displays. Change values may also be specified in hexadecimal.
- A confirm prompt. When you press Enter after having entered new values for one or more fields, a confirm prompt will be displayed. You must answer the prompt with a Y before the program will update the database. You may switch this facility off or change the default from Y to N if you wish.
