Hi John,
As for IIF:
IIF is a function - this means that it must "return" the value
result_array = IIF( condition_array, true_array, false_array );
It works in such a way that each element of condition_array is
checked for true or false, if it is true - corresponding element
of true_array is assigned to result_array if it is false - corresponding
element of false_array is assigned to result_array.
In basic-like language this looks like this
for i = 0 to array_size
if condition_array[ i ] = 1
then
result_array[ i ] = true_array[ i ]
else
result_array[ i ] = false_array[ i ]
end if
next
As you can see false_array is required.

What you want to achieve is possible without
using any IIFs:
buy = cross( close, ema( close, 20 ) AND adx( 14 ) > 15;
// this gives you a buy signal when close rises above EMA 20
// but ONLY WHEN adx( 14 ) is greater than 15
