Installation and environment variables.

I use an iMac running OSX 10.11.4. I have Xcode and Command Line Tools installed.Yesterday I installed IntelŪ Parallel Studio XE 2015 Composer Edition for Fortran OS X evaluation. The installation appeared to be successful. 

As I understand it, I am required to set environment variables. At the command line I entered: which ifort. This gave the location as:

/opt/intel/composer_xe_2015.3.187/bin

However: 

source /opt/intel/composer_xe_2015.3.187/bin/compilervars.csh intel64

and

./opt/intel/composer_xe_2015.3.187/bin/compilervars.csh intel64

produces  line 35: syntax error: unexpected end of file.

What am I required to do? Should I have a licence? No licence was sent to me.
