Odd!...

If you convert the result returned from the macro call into a string before 
assigning it to the variable it works.
Also if you copy the active ingredients from the Rand_Array_Item macro into 
the source it works.
But if you assign the numeric result from the macro to a variable without 
converting it to a string it complains.
Anyway, all of the following examples work.
Maybe someone else could offer an explanation as to why the one you have 
doesn't, but I can't see any material difference.


#include "arrays.inc"

#declare MyArray = array[5] {0, 1, 2, 3, 4};
#declare RS = seed(12345);

#debug concat("Test1: ", str(Rand_Array_Item(MyArray,RS),0,0), "\n")

#declare Test = str(Rand_Array_Item(MyArray,RS),0,0);
#debug concat("Test2: ", Test, "\n")

#declare Test = 
MyArray[floor(rand(RS)*0.9999999*dimension_size(MyArray,1))];
#debug concat("Test3: ", str(Test,0,0), "\n")
