Question

我正在尝试使用以下vim函数在Windows上运行我的sas，但我总是收到错误消息，说系统的参数无效。

有些vim专家可以帮帮我吗？

myy sas安装在：

C：\ Program Files \ SAS \ SAS \ 9.1 \ sas.exe

function! RunSASonCurrentFile()
    " Make sure this is a SAS program file (ends with .sas) so that
    " we don't run SAS on a log file or similar.
    :let checkSASpgm=match(expand("%"),"\.sas")

    " If we did not match .sas in the file name, end this function with
    " a warning msg
    if checkSASpgm==-1
       :echo "*** Current file is not a SAS program.  SAS run has been canceled."
       :return
    endif

    " Ask user if we want to run SAS so we don't accidentally run it.
    :let l:answer = input("Run SAS? Y/N ") 
    :if (l:answer == "Y" || l:answer == "y")

    " If file has been modified, save it before running
    if exists(&modified)
       :echo "*** Saving modified file before SAS run..."
       :w
    endif

    " Run SAS on path/file name (modify to your location of sas)
    :echo "*** Running SAS..."
    "let returntxt = system("/usr/local/bin/sas -nodms " . shellescape(expand("%:p")))
    " The following may work for your Windows system. Comment the line above and uncomment 
    " the two lines below and make them one long line.
    let returntxt = system("\"" . shellescape("C:\\Program\ Files\\SAS\\SAS\9.1\\sas.exe") 
    ".  "\ -nosplash" . "\ -sysin" . "\ " . shellescape(expand("%:p")) .  "\"") 

    " Shows the return messages from the SAS commandline (may be useful
    " if no log produced)
    :echo "*** SAS commandline: " . returntxt

    :call LoadSASLogList()

    :else
    :echo "SAS Run cancelled."

    " endif for the Run SAS? check
    :endif
  endfunction

Vim补丁7.3.443改变了shell转义的行为（由于神秘的Windows shell转义规则，这仍然是一个麻烦点）。事先，如果它包含一个带有空格的（本身引用的）可执行文件，则必须将整个命令行用双引号括起来，现在必须删除它们。请尝试以下方法：

let returntxt = system(shellescape('C:\Program Files\SAS\SAS\9.1\sas.exe') . ' -nosplash -sysin ' . shellescape(expand('%:p')))

这也避免了使用单引号字符串进行一些额外的转义。

如果这是您的函数的确切文本，我认为您在let returntxt = system("\"" . shellescape("C:\\Program\ Files\\SAS\\SAS\9.1\\sas.exe")行中缺少SAS和9.1之间的第二个\。
