If the file .abacus is stored in the directory /home/yourhome
and the file .abacusLicense is stored in the directory
/usr/local/abacus,
then the environment variables should be initialized in the following way
if you are using the C-shell or its relatives:
setenv ABACUS_DIR /home/yourhome
setenv ABACUS_LICENSE_DIR /usr/local/abacus
If you are using the Bourne-shell you might want to use the commands:
export ABACUS_DIR=/home/yourhome
export ABACUS_LICENSE_DIR=/usr/local/abacus
Usually it is convenient to add these instructions to your .login file.
