命令问题

报错现象：Please wait........{ required

原因探究：Stata7 升级Stata 8时，编程方式有变化（ help whatsnew7to8）：4. One change will bite you:  With if exp, while exp, forvalues, and all the other commands that take a brace, no longer can the open brace and close brace be on the same line as the command.  而confall是老命令，基于Stata7运行^[1]。

So because -confall- runs as version 7 and calls -scatter-, it will break on every Stata version since version 9 (or thereabouts).

解决方案

1，定位confall.ado：

which confall

2，根据上面的地址打开confall.ado，如：

doedit "C:\Users\XXX\ado\plus\c\confall.ado"

3，查找，在323行：

scatter  `b' `showvar1' `baicm' `bbicm' `b0' `bfull' `xforgr', `saving' `options' `ytitle' `prxlab'

4，替换为：

version 8: twoway scatter  `b' `showvar1' `baicm' `bbicm' `b0' `bfull' `xforgr', `saving' `options' `ytitle' `prxlab'

5，保存即可。
