How can we set environment variable on Redhat 6.2

Hi,

Sorry to trouble you.

I have installed paralledl studio XE on my PC to working with our software BOOST. The system is Redhat 6.2. Do you know how to setup the environment variable of paralledl studio XE. Besides how can I know the environment is set up correctly.

Besides do you know where I can download the old version of Fortran (Fortran 90 complier v11.1.059). Looking forward to hear from you.
