and the program

  // blah blah

will store the symbolic expression X^2+2*X into k.

Yes, of course, single quotes are fine with upper case X,

but you get an error if you try TEST('x^2+2*x') in home view, so you are forced to use TEST('X^2+2*X'), and then, inside the program, you cannot write something like CAS("subst(k, X='x')"), because nothing gets substututed, (only returns k), so you can't use the function with lower case 'x' for further processing with CAS commands/functions.
