If you work in bash,you can edit the file" ~/.bashrc"!
for example
" export var=abcd "

Hi

How does one include directories to search for in the PATH variable

In RedHat, I have always added some lines to /etc/profile file. for defining new environment variables such as LM_LICENSE_FILE for example you may add the following line at the end of your profile file:
export LM_LICENSE_FILE=/usr/syn/license.dat
and again, if you want to make a more complete PATH env variable: (example)
export PATH=$PATH:/usr/syn:/home/aaa
this adds two new addresses to your path env variable.
