Syntax

logical-OR-expr ? expr : conditional-expr

Remarks

The conditional operator ?: is a ternary operator.

In the expression E1 ? E2 : E3, E1 evaluates first. If its value is true, then E2 evaluates and E3 is ignored. If E1 evaluates to false, then E3 evaluates and E2 is ignored.

The result of E1 ? E2 : E3 will be the value of either E2 or E3 depending upon which evaluates.

The condition operator only is in the TETRA interpreter of a very restricted use since for the E's not the full spectrum of c++ expressions is permitted at present. You can get more exact information about this by looking into the parser for the TETRA c++-interpreter.
