Are you talking about bash? 'Cause bash will fail if you use that syntax. I'm not such I understand the problem. If it is an environment variable, can you see it when you type export in the terminal?

I found a blog talking about your problem: datastage.

If this does not help you, wait for more replies 'cause I'm not familiar with datastage.

this seems like a problem in understanthing.
if im not mistaken, in bash, the varaible is called "var"
the $ at the begining is a way to call teh contents of it. when you set the var, you do this
var="some content"
when you cant to use that var you use
echo $var
or
touch file.$var
