Gen variable w Conditions & Calculation

[Heather Dolphin]

Hi,
I want to create a variable based on a couple conditions and haven't found an example to apply to my situation. I want a variable in dollars for daily pay. My dataset includes 2 currencies. If individuals are in Honduras (coded 2 below) and have a daily rate, I want to calculate that by the exchange rate to know what the rate would be in dollars. For individuals in El Salvador, the currency is already in dollars so I have been trying and failing using these syntax:

gen pago_dia_dol = (pago_dia * 0.040317) if pais == 2 | = pago_dia if pais == 1

here it is in english:
gen daily_pay_dollars = daily_pay * 0.040317) if country == 2 | = daily_pay if pais == 1
Please advise! thank you!

Assuming there are only 1 and 2:

gen pago_dia_dol = cond(pais == 2, pago_dia * 0.040317, pago_dia)

If you have more country codes, then a gen/replace sequence may be easier:

gen pago_dia_dol = (pago_dia * 0.040317) if pais == 2
replace pago_dia_dol = pago_dia if pais == 1
