Yes, I fully agree.
If the behaviour is/will be exactly the same as "if .. then ... else" then it
should
also get a name that shows this clearly.
Therefore, I would still vote for "IfThenElse(.. , .. , ..)".
"InlineIf(.. , .. , ..)" would be ok too but not as clear as "IfThenElse".
If "IIF" in other languages is more of a function in these languages (so both
branches are evaluated in all cases)
then I would not use the same name in Pascal but implement a different
behaviour.
Would this be possible in other languages:
var c : char;
s : string;
c := IfThenElse(Length(s)=0,' ',S[1]);
?
