## $Id$
## $Log$
## Revision 1.21 2003/08/14 10:33:46 gawthrop
## Ignore if and endif
##
## Revision 1.20 2003/08/13 15:49:39 gawthrop
## Don't sort the states when defaulting - leave in implied order
##
## Revision 1.19 2003/08/05 15:29:36 gawthrop
## Now handles ss.r files with implicit zero values
##
## Revision 1.18 2003/08/04 09:10:30 gawthrop
## Now handles steady-state computation for _state.txt.
##
## Revision 1.17 2002/04/28 18:41:27 geraint
## Fixed [ 549658 ] awk should be gawk.
## Replaced calls to awk with call to gawk.
##
## Revision 1.16 2000/10/17 13:45:18 peterg
## split up state and input - different defaults
##
## Revision 1.15 2000/10/17 09:53:05 peterg
## More on logic rep
##
## Revision 1.14 2000/10/17 08:36:56 peterg
## Included logic rep.
##
## Revision 1.13 2000/10/15 09:27:13 peterg
## Better way of generating $infofile
##
## Revision 1.12 2000/10/14 16:11:00 peterg
## Made all variables, states etc lower case
##
## Revision 1.11 2000/10/13 11:07:00 peterg
## Added initialisation for state and input
##
## Revision 1.10 2000/10/13 10:56:07 peterg
## Now uses the full name from the struc file - no need to recreate.
##
## Revision 1.9 2000/10/13 09:55:09 peterg
## Changed state/input name to $4_$3
##
## Revision 1.8 2000/10/13 09:28:16 peterg
## Changed regexp to /\(.*$old.*=\)/
##
## Revision 1.7 2000/10/13 08:56:51 peterg
## Output variables as column, not row.
##
## Revision 1.6 2000/10/13 08:07:24 peterg
## Added state and input - it checks against sympar as well so that
## defined variables may be used here.
##
## Revision 1.5 2000/10/12 19:24:55 peterg
## Corrected output message
##
## Revision 1.4 2000/10/12 17:57:34 peterg
