Thanks Cyrille. That document explains everything!

Leprechaun,

Here is a modified program that works with version 10077:

Code:

ZIN_F:=4000000;
ZIN_REAL:=400;
ZIN_IMA:=400;

EXPORT zin1()
BEGIN
 LOCAL REAL,IMA,n,w;
 LOCAL x,y,z;
 INPUT({{ZIN_F,[0]},{ZIN_REAL,[0]},{ZIN_IMA,[0]}},"IMPEDANCE",{"freq","real","imag"});

 w:=2*π*ZIN_F;
 n:="1+"+w^2+"*r^2*c^2";
 x:="[r/("+n+")="+ZIN_REAL+","+w+"*c*r^2/("+n+")="+ZIN_IMA+"]";
 y:="[r,c]";
 z:=CAS.solve(EVAL(x),EVAL(y));

 RETURN z;
END;

The variables r and c being declared as local is what was messing thing up.
