how to use formula to change 1 to "male" ???

Hi all,

Maybe an easy one but hopefully anyone can help me ..

if I deploy a BAPi I get GENDER = 1

I want to use a formula to change this 1 into "MALE" and if the value is 2 i want to see FEMALE.

And does anybody know an good overview of the formulas that can be use an so extra info about what to fill in, when and how,

the explanation in VC is not always clear to me

thanks !
