Other If control flow

PaulS

Problem

It would be nice to have another If without the then and else.

If (condition, result if true, result if false)

Who Would This Help?

It's useful for small comparisons and takes only 1 line of code instead of 5.

If (condition, result if true, result if false)

Instead of

If condition Then
  result if true
Else
 result if false
End If

That is not control flow, it’s a function.

Similar to Choose in some BASIC flavors. In 4D you can pass either Boolean or Integer as criteria to Choose command, with Boolean you get what you’re asking for, with integer you can choose to return value with that index if passed to command.

madamov I think the term of art is "ternary conditional".

I think it was IIF() ("immediate if") in VB.NET (inherited from VB6) and later replaced by IF() which had short circuit evaluation that IIF() lacked, and also did not take just Object args, avoiding the attendant performance penalties due to (un)boxing.

I use the similar ternary operator occasionally in c# but slightly prefer explicit If/Else blocks as clearer / easier to read. That's partly a result of the terse C# syntax:

bool expression ? true result : false result;

I don't feel strongly one way or the other on this one. "Nice to have" if it's easy to implement. Some folks will feel more strongly, I'm sure.
