comment Plotting a list in real time
@Szabolcs why is it that when I evaluate your commands the whole list is being plotted for a second and then after this delay only it starts plotting from x = 1?

@rm-rf you're correct, I want to display a pre-computed list of points sequentially

comment Import an SPSS, SAS, or STATA file into Mathematica
No luck so far. I have submitted the data file to Wolfram|Alpha, I think it would be a great addition to their search engine.

Just perfect. So of course mathematica can do it!

comment Check if an inequality holds among the solutions returned by Solve
@Mr.Wizard OK thanks almost there... why if I add a condition in the Reduce, for example Module[{sol}, sol = Solve[{a == 3*c, b == 2*a}, {a, b}]; Reduce[{a < 7 b, c == 2} /. sol] ] I get the error message "Reduce::naqs: "{3\ c<42\ c,c==2} is not a quantified system of equations and inequalities""? How to reduce multiple equations but keeping the replacement rule?

comment Check if an inequality holds among the solutions returned by Solve
ok that would be the best solution except that sol is not a local variable. I tried Module[{sol}, sol = Solve[{a == 3*c, b == 2*a}, {a, b}] Reduce[a < 7 b /. sol] ] but this gives messages like "sol$69027 is neither a list of replacement rules nor a valid dispatch table"

@Öskå this would work but a and b are not local in this case.

but if I try that I get as output {c \[Element] Reals && 3 c < 42 c} which is not the same as the "normal" output c > 0
