I am wondering how to subset multiple rows in a dataset in SAS, any codes recommended? Thanks!
Take a look at the WHERE statement. That's a common tool for the task, and can be used in both DATA and PROC steps. Its chief limitation is that it must base the subsetting decisions on variables that already exist in the incoming data set.
If you need to perform calculations first, and base the subsetting on the calculated values, take a look at the IF statement. (Not IF/THEN.) It's valid in a DATA step only.
Please supply some example "have" and "want" data rows to illustrate your question.
Subsetting datasets as such is a very easy task, so you seem to have some additional requirements.

Another option if you wish to subset based on a list of values: use SQL inner join/sub-query with a look-up table.
