Dear STATA lister
basic question, i am trying to recode column with list of names that
have been entered in different ways.

var1
EFA, Panadol
EFV, Panado
Antibiotics, Efavirenz


I am trying to generate new variable var2 to have one value for EFV
gen var2 = var1
recode var (?EFA? = EFV) (?EFV? = EFV) (?Efavirenz? = EFV)

Recode does not accept text, any tips how to go around it?


Thank you in advance and best regards
ziad
