Condition command stata

[Madu Abuchi]

I want to create a new variable (ageT) with the -cond- programming function. Is there any way I efficiently code my repetitive example below?

set obs 100
gen agegrp = runiformint(1,5)

gen age1 = cond(agegrp==1,0,.)
gen age2 = cond(agegrp==2,2,.)
gen age3 = cond(agegrp==3,4,.)
gen age4 = cond(agegrp==4,6,.)
gen age5 = cond(agegrp==5,8,.)
egen ageT = rowmax(age1 age2 age3 age4 age5)

Thanks

Your desired variable can be generated in a single line, taking advantage of the fact that (0,2,4,6,8) is a simple arithmetic sequence.

gen ageT = 2*(agegrp-1)
