Under Unix, there are two commands that invoke Mathematica. math invokes the text-based version and mathematica invokes a notebook version. The Mathematica book seems to claim that you get the same results whichever you invoke. But you don't. The version of Mathematica which we run is Solaris 3.0 (August 21, 1997) This is the response to $Version for both math and mathematica. However, the program txt= StyleBox[ RowBox[{"number ",n," ", FractionBox["roman", StyleBox["greek",FontSlant\[Rule]"Italic",FontSize\[Rule]24, FontFamily\[Rule]"Times",FontColor\[Rule]Hue[0]]]}], FontSize\[Rule]18,FontFamily\[Rule]"Arial"]; n=5; pict = Plot[Sin[x],{x,0,7},Epilog\[Rule]Text[DisplayForm[txt],{3,.7}]]; Display["plot.eps", pict,"eps"]; gives rise to Postscript files that are VERY different. In particular, under mathematica the Postscript contains several lines which refer to italics (ignoring case), whereas under math there are no lines in the Postscript file referring to italics. Is this a bug? Is there a workaround? It is far more inconvenient for me to use the front end than the text-based version. In any case, it seems to me that Mathematica is not living up to the claims made in the Mathematica Book. David Epstein
