Question

这让我发疯了。我试图掩盖在网格安装期间使用的SAS计划文件的特定行中的所有特殊字符，这些文件已放入数据集中：

if test_item = %str(<Machine Id=%'$machine:)&mach_num.%str(' Name=')&mach_name.%str(%'>) then end2 = end1;

日志打印在下面。我看到正在出现假脱机错误（可能是因为某些内容未被正确屏蔽），但是日志中的MPRINT表明宏变量编译已正确执行。

SYMBOLGEN:  Macro variable FUNC_VAR resolves to test
MPRINT(PLAN_FINDER):   data test_plan4;
SYMBOLGEN:  Macro variable FUNC_VAR resolves to test
MPRINT(PLAN_FINDER):   set test_plan3;
MPRINT(PLAN_FINDER):   by ret_sort;
MPRINT(PLAN_FINDER):   retain end2;
388: LINE and COLUMN cannot be determined.

ERROR 388-185: Expecting an arithmetic operator.

MPRINT(PLAN_FINDER):   if test_item = <Machine Id='$machine:2' Name='Metadata Server'> then end2 = end1;
MPRINT(PLAN_FINDER):   else if end1 = 1 then end2 = end1 + end2;
MPRINT(PLAN_FINDER):   run;

有人可以告诉我我做错了什么吗？

代码：

%macro test(func_var, mach_num, mach_name);

data &func_var._plan4;
set &func_var._plan3;
by ret_sort;
retain end2;
if test_item = %str(<Machine Id=%'$machine:)&mach_num.%str(' Name=')&mach_name.%str(%'>) then end2 = end1;
else if end1 = 1 then end2 = end1 + end2;
run;

%mend;

%test(test, 2, Metadata Server);

test_item中字符串的预期解析度：

<Machine Id='$machine:2' Name='Metadata Server'>

谢谢

我不知道您为什么认为您需要掩蔽。这可能比我想的要复杂，但对我来说似乎也有很多不必要的工作。

这对我来说是预期的工作，请让我知道它是否可以用于您要尝试的工作。

test_item = "<Machine Id='$machine:&mach_num.' Name='&mach_name'>"

在数据步骤中进行测试：

%let mach_name=Metadata Server;
%let mach_num=2;

data test;
test_item = "<Machine Id='$machine:&mach_num.' Name='&mach_name'>" ;
run;

proc print data=test;
run;

结果：

test_item = <Machine Id='$machine:2' Name='Metadata Server'>
