## Revision 1.16 2001/07/26 04:07:28 gawthrop
## Changed a to w on open (Geraint's suggestion)
## Explictly close files
##
## Revision 1.15 2001/07/23 23:24:02 gawthrop
## Now only writes to type.sh and cbg.m when causality is complete
##
## Revision 1.14 2000/12/28 12:16:13 peterg
## *** empty log message ***
##
## Revision 1.13 1998/07/27 20:30:12 peterg
## *** empty log message ***
##
## Revision 1.12 1998/07/10 08:43:46 peterg
## Added -I switch
##
## Revision 1.11 1998/01/23 13:29:54 peterg
## $RMATRIX --> $MATRIX
##
# Revision 1.10 1996/12/04 21:51:02 peterg
# Now uses filenum instead of line name.
# Uses fopen
#
# Revision 1.9 1996/11/06 15:49:33 peterg
# Cahged $MATRIX to $RMATRIX
#
# Revision 1.8 1996/08/25 09:31:49 peter

# The causal BG is described by four matrices
# (the same structure as the acausal BG except that Causality is 1 ot -1):
# junctions: describes the junctions -
# Column 1 Index of component (see components)
# Column 2.. Indices of bonds on junction (see jbonds)
# rows may be padded with zeros
#
# cjbonds: describes the true bonds -
# Column 1 Index of component (see components)
# Column 2 Direction
# 1 away from junction
# -1 towards junction
# Column 3 Effort causality
# 1 stroke at arrow end
# -1 stroke at other end
# 0 no stroke (ie acausal)
# Column 4 Flow causality
# 1 stroke at arrow end
# -1 stroke at other end
# 0 no stroke (ie acausal)
# Columns 5:6 x,y coordinates of non-arrow end (in Fig)
# Columns 7:8 x,y coordinates of arrow end (in Fig)
#
# mbonds: describes the modulation bonds -
# Column 1 Index of component at non-arrow end
# Column 2 Index of component at arrow end
# Columns 4:5 x,y coordinates of non-arrow end (in Fig)
# Columns 6:7 x,y coordinates of arrow end (in Fig)
#
# components: describes the comonents -
# Column 1 Type of component
# 0 0-junction
# 1 1-junction
# 2 R component
# 3 C component
# 4 I component
# 11 TF component
# 12 GY component
# 13 A component
# Column 2 Flag for explicit junction
# 4 Explicit component (4 means text type)
# 0 Implicit component
# Column 3-14 fig file information (see fig documentation)
#
# Lists of under- and over-causal junctions are displayed.
