Good evening.
thanks for your support!

Could u give me one tip.
I user C target and want to parse such input

"a = 3.14
f(x) = 3x^2 - 4x + 2

print "The value of f for " a " is " f(a)
print "The derivative of " f() " is " f'()


list variables
list functions

g(y) = 2y^3 + 6y - 5
h = f + g
print h()"

I use this tutorial
http://jnb.ociweb.com/jnb/jnbJun2008.html

but parser fails.. when finds empty lines. It's correct, but how can i fix  
it? It's common problem for all languages. Programmer can input some empty  
lines between constructions to improve code readability...

Michael
