st: Changing neg into pos values

["Ziad El-Khatib" <Ziad.El-Khatib@ki.se>]

Dear STATAlister,
i have variable var1 containing both of pos or neg values, i want to
create new variable var2 equal to var1:
  to have var2=100-var1 if var1 >0
  to have var2=100 plus the positive value of var1 if var1<0 (for
example if var1= -4 then var2 would be = 100 + 4 = 104

any tips?


Thank you in advance and best regards
ziad
