DOes anyone know how to program the following SPSS code in SAS? I need to do exactly this but in SAS! I do have access to SPSS at all!

I would expect something sampling to indicate the number of records to select or a rate to select records from a base data set. Unless that is the use for the variables inc_prob_1 and inc_prob_2. In which case these would likely be the equivalents of _nsize_ variable in a SAMPSIZE=dataset for use in Surveyselect or _rate_ in a SAMPRATE= dataset.
Proc surveyselect would be the procedure, with a Strata statment having the stratlist variables and a cluster cluster statement with the cluster variable. Assuming I am rgith about your inc_prob_1 then your samprate data set would have to be sorted in terms of the strata combinations.
Since I have no idea what the output of the SPSS looks like I can't suggest any other specific options.
