Variable looping

[Guest]

Cheers, Here is the code that I have

gen date1990 = amo + ayear
gen date1992 = bmo + byear
gen date1994 = cmo + cyear

and so on through date2014. I am wondering if this is loopable?

tokenize "`c(alpha)'" 

forval y = 1/13 { 
    local Y = 1988 + 2 * `y'
    gen date`Y' = ``y''mo + ``y''year
}

Some of the small arithmetic behind that -- working out that there are 13 instances -- should have been in the question.
