Ternary operator

I can't seem to find the information online, maybe because I'm searching
for a negative.

I know that at one point the RPG compiler folks floated the possibility
of a ternary operator (in Java, it's the "?", as in:

   maxval = (val1 > val2) ? val1 : val2;

In this, the condition to the left of the "?" is tested, and if true,
the value to the left of the ":" is used, otherwise the value to the
right is used.

Did this show up in V5R3?
