First, yes, the atmospheric pressure can affect the melting and boiling points to some degree. If you put water under a vacuum at room temperature, it will boil. However, the effect is not as significant for solids. Secondly, are those new temperatures correct? I get 1261K or 988 deg C for the first two, and 2476K or 2203 deg C for the second. I'm still pretty sure about the intrepetation of '.', '\' and '/' as solid, liquid, and gas (as it fits in will with later statements), but the temperatures no longer are close with the expect MP of iron of 1535 deg C. In order to match this, the conversion between a TCtemp unit and kelvins must be .087075 K/TCtemp unit, instead of .060667. This causes the other temperatures to be extremely high.
