Hi Yanzhip

You could generate a subset with the set elements you want:

Set
     Year         /2014*2033/,
     Year6(year)   'Six step years';

scalar         timestep       /6/ ;

year6(year)$(mod(ord(year)-1,6) = 0) = YES;

disply Year6;

----     13 SET Year6  Six step years

2014,    2020,    2026,    2032
