Question

我在SAS中编程，想使用LUA编写一个创建xml文件

因此，首先，我启动proc LUA并传递文件名 ;

%let file = \\ergo\applications\CRS\BSUG\new.xml;

proc lua restart;
submit;
    local file_name = sas.symget("file")
    print (file_name)

-接下来，我打开文件进行写入，编写并关闭文件

    file = io.open (file_name, "w")
    file:write ("<test>", "\n")
    file:write ("write to file", "\n")
    file:write ("</test>", "\n")
    file:close()

-当然也要停止LUA

endsubmit;
run;

/ *这有效：文件是使用此内容创建的

<test>
write to file
</test>

但是它会在日志中显示以下消息

NOTE: Lua initialized.
\\ergo\applications\CRS\BSUG\new.xml

我不知道这是纯粹的LUA问题，还是与SAS中的proc LUA相关的问题。

注意：当我注释掉io.write语句时，我仍然遇到问题。

您的代码对我来说很好（在SYSVLONG=9.04.01M3P062415，SYSSCP=LIN X64上）。

也许尝试以下略有不同的方法？

%let file = %sysfunc(pathname(work))/new.xml;

proc lua restart;
submit;
    local file_name = sas.symget("file")
    print (file_name)
    file = io.open (file_name, "w")
    io.output(file) -- sets default output
    io.write ("<test>", "\n")
    io.write ("write to file", "\n")
    io.write ("</test>", "\n")
    io.close(file)
endsubmit;
run;

从proc LUA中读取访问冲突打开文件
