INPUT() and complex numbers?

[DrD]

I think I may have discovered a way to input a complex number:

1. Predefine a variable as a complex number: zl:=0+0i;
2. Execute the INPUT() function on it: INPUT(zl); // <== 50+25i, returns 1.00
3. Now EVAL the variable: EVAL(zl); ==> 50.00+25.00*i

EVAL((zo-50)/(zo+50)) ==> 0.06+0.24*i


Predefining zl:=0+0i worked when entered in the HOME command line, but results in a syntax error when zl:=0+0i; is entered in a ppl program.
