Re: st: finicky graph parsing

["Michael N. Mitchell" <Michael.Norman.Mitchell@gmail.com>]

Dear Alan

  You actually should be getting an error on all of these because an extra comma has been 
included in the second scatter command, shown again below with *,* around the extra comma.

   (scatter P del2, c(l) s(i) clcolor(red) clwidth(thick) *,*xtitle("actual change (mm 
Hg)") ytitle("probability") legend(order(1  "same operator" 2  "different operators"  ) 
cols(2)    )  )

  The parser probably forgave you when the comma had no spaces around it, treating it as 
though the comma were a space.

Hope that clarifies.

Best regards,

Michael N. Mitchell
