st: graph doesn't work

[Leonelo Bautista <lebautista@wisc.edu>]

None of my graph commands seem to work. All of them result in the same error message:

 

twoway line pas edadr

invalid line in scheme ,

*!  version 1.0.7   23oct2003

r(9999);

 

graph (scatter pad edadr)

invalid line in scheme ,

*!  version 1.0.7   23oct2003

r(9999);

 

Just in case this has something to do with it, I’m using Stata 8.0, updated to October 31^st, 2003.

Any suggestions about what may be wrong?

Thanks,
