tableBASE version 5 library expansion limits

To find the expansion limit, start by finding the row into which your source library size would fall (see Table 9). For example, if your source library was 100,000 blocks or 700 cylinders then you would be in the first row under the Lower Limit. The expansion limit would then be the number of blocks or cylinders listed under the Upper Limit for that row. In the example given, the expansion limit would be 168,000 blocks or 746 cylinders. This means that your target library must be less than 168,000 blocks or 746 cylinders.

Note:

* For 3120 blocksize the maximum size BDAM = 983,025 blocks / 65,535 tracks / 4369 cyls (BDAM size stored in half-word).

Limits for conversion back and forth between V5 and V6 (3120 blocksize libraries) is 836,550 blocks / 3718 cyls BDAM / 4290 cyls VSAM.

These restrictions to the expansion of tableBASE libraries do not apply to libraries in the Version 6 format. Once converted, Version 6 format libraries may be expanded. However, expansion will mean that they can no longer be converted back to the Version 5 format.
