Pytanie Problem Statement SAS expressions are provided in the form of text strings, say: "A and B or C", "A * B + C", or "42 = A + B + C", where A, B , and C are variables from some data set HAVE. Evaluate those expressions using vales from HAVE.
Przykład Problem Statement - Example code A + B A = B A or B A 17 100 1 B 42 101 0 result result = EVALUATE(code);
Przykład Problem Statement - Example code A + B A = B A or B A 17 100 1 B 42 101 0 result 59 result = EVALUATE(code);
