 [[ACC]] doesn't support the ternary operator '?:', but [[BCC]] and [[GDCC]] do. To emulate it in ACC, ACSUtils implements the following trivial function: [[ACC]] doesn't support the ternary operator '?:', but [[BCC]] and [[GDCC]] do. To emulate it in ACC, ACSUtils implements the following trivial function:
  
-''any cond(bool condition, any whentrue, any whenfalse)''+''any cond(bool condition, any a, any b)''
  
-If ''condition'' is true, function returns ''whentrue'', otherwise it retuns ''whenfalse''.+If ''condition'' is true, it returns a, otherwise it returns b.
  
 The only difference is that all arguments are evaluated before the function is called. This means that ''cond(x, f(), g())'' will call both ''f()'' and ''g()'', while ''x ? f() : g()'' will call only one of them. The only difference is that all arguments are evaluated before the function is called.

 +if (PlayerTeam() == TEAM_BLUE)
 +    color = CR_BLUE;
 +DrawSomething(color);
 +</code>

 +With ''cond()'':

 +DrawSomething(cond(PlayerTeam() == TEAM_BLUE, CR_BLUE, CR_RED));
