So you cannot declare polyphonic string variables, nor can you + variables and real number variables (scalars). + So you cannot declare polyphonic string variables, nor can you declare polyphonic array variables.

And with string variables and array variables, the - required amount of memory would be much higher than with simple integer - variables. + required amount of memory would be much higher than with simple integer or + real number variables.
As summary, the following are guideline rules describing when you should
