don't count. Traditional mainframe systems (and VMS) do, in native mode (i.e. not in their POSIX environment, if any). Don't be silly. In MVS, VMS etc., the maximum length of...

Nit. That will work on an HP-48, but on an HP-35, the result will be a stack with 4 in the X register, and a 3 in the Y.
The HP-35 uses the original 4-level stack, XYZT, where X is the data entry line and T is the "top" register that retains its value on any operation that doesn't specifically change it. Pressing the Enter key on the HP-35 copies Z to T, Y to Z, and X to Y, leaving X unchanged. Pressing 2 Enter will leave 2 in both X and Y; pressing x (multiply) will multiply X and Y, leaving the result in X, (and copy Z to Y, T to Z, and leave T unchanged).
The HP-48 has a (conceptually) unlimited stack with numbered levels, and a separate command entry line. Pressing 3 Enter will roll the stack up and insert the value 3 at level 1 of the stack. Pressing 2 Enter will again roll the stack up (moving the 3 to level 2), then write the 2 to level 1. pressing x (multiply) will multiply the value at level 2 by that at level 1, leaving the result at level 1 (and rolling down any of the stack above).
Note that the key sequence 3 Enter 2 x will work on either device, multiplying 3 by 2 and leaving the result in X or level 1.
