I do not understand your code.

What should work to let the second function use the first:

ans=function2(function1(input))

Make the variable to global. Check the below code.

function 1() global x; x = 10; x = x+10

return

function 2() global x; global y; y = 0; y = y+20; display(x); return

function test() global x; global y;

   display(x);

   display(y);
return
