- Ummm, no. To my knowledge, SVR4 doesn't EXIST for the WECO-based 3B2s (e.g.
- all 3B2s other than the 3B2/1000R3 models, which are Mips-based). If it does
- exist, we've certainly never ported to it.

- Do you have any idea how the support matrix explodes if you try to support
- the last several revs of the O/S (and I'm not talking about *different
- versions* of the O/S, e.g. SVR4, I'm talking just maint upgrades, e.g. 3.2 to
- 3.2.1 to 3.2.2 to 3.2.3 to 3.2.4)?

-
- We do nothing to break operation on old releases; to my knowledge, 4GL ported
- using 3.2.3 will run fine on 3.2.1. However, any changes in the O/S that *do*
- break backward compatibility are simply not under our control; therefore, we
- can't *guarantee* compatibility on combinations which we have not certified.
