What does the $ in front of environment variables do?

Sometimes I see the $ in front of environment variables, but at other times it's not there. What is the difference?

Hi,
It is not sometimes.All Cutomize,Parallel,Compiler,Operator Specific,Reporting and User Defined environment variables(that are defined at project level) are starts with $ but the environment variables which you explicitly define in your job properties,it does not required $ sing.

The conventions for shell and environment variables in UNIX is:

when the variable is named, it is not preceded with $

when the value of the variable is retrieved, the variable name is preceded with $

DataStage follows this convention for using environment variables.
