I used the SEWARD_MEM variable because my runs were terminating in errors,
and after doing some research, I found out that I should use it, and it
worked (URL below).  I will try a run with and without it to see if it will
change anything.  With regards to the R1(I,J,K,L), I wasn't sure if having
multiple variables named e(i) or method(i) would be a problem for the
tables.  I will try changing what you have suggested and let you know what
happens.  Thank you!
