For Stata your best best is probably to stack all 150 datasets into one 
long data frame and add an id variable, so you can then -by id:- your 
analysis.
   big.data.frame <- do.call("rbind", the.list.of.datasets)
will stack them for you and
   big.data.frame$id <- rep(1:150, sapply(the.list.of.data.sets, nrow))
will make the id variable.
