如下代码：#delimit;tsline pforcount pdomcount pdom_forcount
        , lwidth(medthick) name(all, replace) scheme(s2mono)
        graphregion(color(white) fcolor(white) icolor(white))
        title("All countries" " ")
        legend(label(1 Foreign) label(2 Domestic) label(3 Partnership) rows(1))
        tlabel(1867 "1867" 1900 "1900" 1925 "1925" 1950 "1950" 1975 "1975" 2005 "2005")
        xtitle("") ytitle("Share of countries with legislation")
        yscale(range(0(0.2)1)) ylabel(0 0.2 0.4 0.6 0.8 1.0, format(%9.1f) angle(0));
报错：, is not a valid command

若不使用#delimit命令，使用常规换行符///则可顺利运行，请教原因！谢谢各路大神！
