RE: Ternary operator

["Bob Cozzi" <cozzi@xxxxxxxxx>]

To be narcissistic, I use this:

  Eval  mxval = max(val1:val2:val3)
But then I use the RPG xTools.

Subject: Re: Ternary operator

I have seen this operator construction in several languages, although
my memory fails me.  Why is this better than using a standard if
statement?

if (val1 > val2)
  then maxval = val1;
  else maxval = val2;  {I am sure my syntax was wrong ;->}

It is certainly more obscure, and harder to figure out if you haven't
seen it before.  And heaven help the reader if the spaces are removed.
     maxval=(val1>val2)?val1:val2;
