Scientific calculators that have formula/equation memory

Really? With the free42 I can write a program that is nothing else than a formula (indeed like a macro for the keystrokes), using registers to hold the variables in input.
On a 506w I can save a formula like 'A^2 + B + 35* C' where at first I fill the registers A, B, C with the data, then recall the formula (say, saved in F1), and execute it.

Is this feature removed in the dm42? Or is it me using a wrong terminology?
