Perl中两个verialbes的串联

朋友，

请问任何机构可以指导我如何连接两个变量的值?

我已经用Google搜索了它，发现了很多方法，但是每当我尝试串联时，都会失败.

我尝试了以下几行:

Hi Friends,

Could any body please guide me how to concatenate the value of two variable?

I have Googled for it and found lots ways but whenever I tried to concatenate I got failed.

I have tried the following lines:

print "Enter the name";
$baseStream = <> ;
$b = 1;
$strName = "${$baseStream}_Strm_${b}";
print $strName;

如果输入名称XYZ，则预期输出为:XYZ_Strm_1

但是在命令行中，我的输出为:
XYZ
_Strm_1

我只是不明白为什么输出会分成两行.

请帮帮我.

提前谢谢.

If I entered the name XYZ then expected output is : XYZ_Strm_1

But in command line I am getting output as :
XYZ
_Strm_1

I just don''t understand why the output is got split in two lines.

Please help me.

Thanks in advance.
