.SS Execution
In the edge bundle table of the workstation state list, the given
index is associated with the specified parameters.
.LP
The edgewidth scale factor is a scale factor applied to nominal edgewidth.
During structure traversal, the edgewidth scale factor is multiplied
by the nominal edgewidth on a workstation. The result is mapped by the
workstation to the nearest available edgewidth.
.LP
Edge colour is a general colour, either an indirect or a
direct colour in a specified colour model. If an indirect colour is
specified and the specified colour index is not available during
structure traversal, then colour index one is used.
.LP
The extended edge bundle table in the workstation state list has
predefined entries taken from the workstation description table. A
number of these entries are predefined for every workstation of category
\s-2OUTPUT\s+2 or \s-2OUTIN\s+2. Any table entry, including the predefined
entries, may be redefined with this function.
.LP
When area defining primitives are displayed during structure traversal,
the current edge index in the \s-2PHIGS\s+2 traversal state list
refers to an entry in the extended edge bundle table. If the
current edge index is not present in the extended edge
bundle table, then edge index one is used. The setting of the
corresponding Aspect Source Flags(\s-2ASF\s+2s) determines which
aspects in the entry are used.
.RE
.SH ERRORS
.IP 003
Ignoring function, function requires state (\s-2PHOP, WSOP, *, *\s+2)
.IP 054
Ignoring function, the specified workstation is not open
.IP 059
Ignoring function, the specified workstation does not have output capability
(that is, the workstation category is neither \s-2OUTPUT\s+2,
\s-2OUTIN\s+2, nor \s-2MO\s+2)
.IP 100
Ignoring function, the bundle index value is less than one
.IP 103
Ignoring function, setting this bundle table entry would exceed the maximum
number of entries allowed in the workstation bundle table
.IP 107
Ignoring function, the specified edgetype is not available on the
specified workstation
.IP 110
Ignoring function, the specified colour model is not available on the
workstation
.IP 113
Ignoring function, the colour index value is less than zero
