## $Id$
## $Log$
## Revision 1.8  1999/04/20 00:55:40  peterg
## Changed <= to < in switchopen.m
## Removed switch.m generation - redundant
##
## Revision 1.7  1999/04/02 06:30:37  peterg
## New _switchopen
## Removed switcha
##
## Revision 1.6  1998/10/01 18:20:50  peterg
## Split up the three if conditions on the switch and state value into
## three separate ifs. This is because p2c seems to generate incorrect
## code id just the one if is used (???).
##
## Revision 1.5  1998/10/01 16:05:34  peterg
## Separate switch.m file for euler and implicit integration
