Hello, Assuming that A is sequential and inclusive (1, 2, 3 ... n),
the following code should do the trick (no if statements required).
* create sample file of variable A;
input a @@;
4 2 3 1 3 5 1 4 2 4 3
* create a lookup table for conversion, specifying values of B in the
order corresponding to the 1, 2, 3... of A;
input b @@;
9 13 27 37 49
* convert A to B;
set lookup point=a;
