It's not about theory, it's about real application. Does anyone have experience that code written in DS2 actually executed faster than similar code written in 4gl? Examples found on the Internet are artificial and not useful in practical use. Has anyone actually had faster code that executes multi-threaded? ... View more

In regular 4gl I do: data table_input; X = 7; output; X = 3; output; X = 7; output; X = 2; output; X = 7; output; X = 4; output; X = 7; output; X = 4; output; X = 3; output; X = 7; output; run; data _null_; set table_input end = eof; if _n_ = 1 then do; length COUNT 8; declare hash h (suminc:1, keysum:'COUNT'); h.definekey ('X'); h.definedone (); end; h.ref (); if eof then h.output (dataset: 'table_output'); run; I get the number of occurrences of the variable X as the results. It's ok. How to do it in DS2? There is no keysum variable in DS2, I don't know how to add a Count that has the number of occurrences of X in the output table. ... View more
