hp 28s - creating nested lists

[mbrethen]

It compiles, but as written it gives an error message about a bad 'FOR statement.' I checked for typos.

The reference manual shows the HP 28 FOR/STEP statement as:

start finish FOR name loop-clause increment STEP

increment must be a real number.

For example:

Code:

1 11 FOR x x SQ 2 STEP

places the squares of the integers 1, 3, 5, 7, 9, and 11 on the stack.
