Among the options of -roccomp- all twoway options are allowed. In Stata 7
-key()- and -symbol()- were valid twoway options. However, in Stata 8 -key()-
is replaced by the much more powerful legend-options (see -help
legend_options-), and -symobl()- is replaced by -msymbol()-. Within the
parentheses of -msymbol()- the marker symbols were no longer specified with
single letters, but with words, two letter abbreviations or one letter
abbreviations. Marker symbols for different data areas therefore has to be
separated by blanks.
A valid syntax of you command therefore might be (not tested):
. roccomp Dep in1 in2 in3 in4 in5, graph yline(0) xline(0)
msymbol(oh Th Sh p i) legend(off)
which uses "hollow" circles, triangles and squares. Change -msymbol()- to
msymbol(o T S p i) if you want filled marker symbols (also see -help
marker_options).
Another poster has recommended to enter -version 7- before entering the
command. Personally I would not do this. After all you have bought Stata 8,
so you might want to use it. If you enter -version 7- you will not have
access to the new graphics capacities, and many other new features of Stata
8.
Hope this helps
