Setting IDL environment

If you are using CShell open your ~/.cshrc file and add the following line wherever you want to set your IDL directory. Then, close your terminal and open again. From now one whatever .pro files you save in your ~/idl directory will be readily accessible whenever you start idl, does not matter from which path.

setenv IDL_PATH +$HOME/idl:+$IDL_DIR/lib:+$IDL_DIR/contrib:+$IDL_DIR/examples
