如何让 Stata 在每次循环迭代中等待用户输入？

Question

我遇到用户需要手动 review/edit 数据的情况。我想一次向他们展示大块数据。我正在使用循环执行此操作。我的问题是让循环等待用户说她已经完成了一个块，然后再移动到下一个块。

我尝试了 set more on、pause on 和 _request，但没有成功。这是我使用一些假数据设置的示例：

clear

set obs 100
gen id   = int( 5*uniform() )
gen var1 = uniform()

levelsof id, local(ids)
foreach id of local ids {

    edit if id == `id'
    
    /* 
       pause, 
       wait for user to hit any key in 
       the Command Window before moving
       to the next iteration
    */ 

}

根据 Nick Cox 的评论，这是我的解决方案。

clear

set obs 100
gen id   = int( 5*uniform() )
gen var1 = uniform()

levelsof id, local(ids)
foreach id of local ids {

    edit if id == `id'
    
    * user must type _next_ in Command Window for next iteration
    local cmd 0
    while ("`cmd'" != "next") {
        
        display _request(cmd)
        local cmd "$cmd"
        
        /* here's the trick: the edits (replace var1 = bla in bla)
           are captured by _request(). I need to send the replace
           command back to stata */
        if ("`cmd'" != "next") {
            `cmd'
        }
    }
}
