- Bob Roberts asked if it was possible to nest data steps. Asserting a
- null proposition (that something is not possible) is risky but I'll chance
- it. I asked SI the same question recently and Tech Support confirmed my
- suspicion that this was *not* possible. There are problems with marking
- the step boundaries, not to mentioned parsing the syntax, that prevent
- data step nesting.

- However, if all you wanted to do to the SECONDB data set was to perform
- table lookup, you can employ the technique of using the Format procedure
- and the Put, Input functions to add the additional variable(s) to the
- SECONDB data set. Release 6.07 lets you use a SAS data set to define
- the Format procedure ranges, which is a very helpful feature to have for
- this type of activity.
