Checking parallelism PROBLEM... (SOLVED!)

OK!

Finally Got it!

here's the code for getting the: is_parallel(); command to work from inside of a non-CAS program.

EXPORT test()
BEGIN
LOCAL a1,b1,c1,a2,b2,c2,aa;
INPUT({{a1,[0],{7,15,1}},{b1,[0],{35,15,1}},{c1,[0],{64,15,1}},{a2,[0],{7,15,2}},{b2,[0],{35,15,2}},{c2,[0],{64,15,2}}},"I HAVE...",{"A₁:","B₁:","C₁:","A₂:","B₂:","C₂:"},{"Enter Coefficient A: (Any Real Number.)","Enter Coefficient B: (Any Real Number.)","Enter Coefficient C: (Any Real Number.)","Enter Coefficient A₂: (Any Real Number.)","Enter Coefficient B₂: (Any Real Number.)","Enter Coefficient C₂: (Any Real Number.)"});
aa:="is_parallel(line("+a1+"*x+"+b1+"*y+"+c1+"=0)"+",line("+a2+"*x+"+b2+"*y+"+c2+"=0))";
aa:=CAS(aa);
print();
print(aa);
END;


I have to thank Han for his personal support and also to rprosperi for referring me to Han's tutorial.

Thank you all!
