## Revision 1.16.2.1  2002/09/03 23:44:43  geraint
## adding global optimisation (-optg).
##
## Revision 1.16  2002/09/03 19:34:15  geraint
## Write EdX regardless - csex is needed to create ode when not optimised.
##
## Revision 1.15  2002/08/29 15:45:20  geraint
## Tests for existence of matrix before entering shell loop.
## Tests for existence of expression before attempting to write or optimise.
