The KEYCOMPRESS option specifies the type of key compression in use.
KEYCOMPRESS=integer | 0 | Key compression is not in use |
| 1 | Duplicate key compression is in use |
| 2 | Leading character compression is in use |
| 4 | Trailing space compression is in use |
| 8 | Trailing null compression is in use |
| Default: | 0 |
To specify a combination of the various types of compression, add together the appropriate numbers. For example, 3 specifies duplicate key compression and leading character compression.
