When you say "Why is BOOTSTRAP not there when it .... runs perfectly when specified?" Does it run perfectly, with whatever method you ran with Bootstrap with the exact same data?
Which version of which interface are you copying that picture from? Perhaps the interface doesn't have the option because it hasn't been updated since the Bootstrap option was added to the procedure?
The documentation tells me that if you use Bootstrap as Varmethod (which is where I have to assume you are attempting this hard to tell from a picture) that there must be at least 2 PSU in each stratum unless you use a REPWEIGHTS statement. So perhaps you need different data of the Repweights before the bootstrap is available.
