<h2>Package:</h2>

<p>
'

<pre>
'

<b>make-shared-environment</b> <i>env</i>
'

<h3>Arguments and Values:</h3>
'
53
'
54
<p><i><code>env</code></i>---an <i>unification-environment</i>.
'
55
<p><i><code>unification-environment</code></i>---a new <i>unification-environment</i>.

<h2>Description:</h2>
'
60
'
61
<p>The function MAKE-SHARED-ENVIRONMENT constructs a new
'
62
object of type UNIFY:ENVIRONMENT. The new
'
63
<i>unification-environment</i> shares the frames already present in <i>env</i>.</p>
'
64
'
65
<p>It is guaranteed that extending <i>unification-environment</i>
'
66
will not change <i>env</i>.</p>
'
67
'
68
'
69
<h2>Affected By:</h2>
'
70
'
71
<p>None.</p>
'
72
'
73
'
74
<h2>Exceptional Situations:</h2>
'
75
'
76
<p>None.</p>
'
77
'
78
'
79
<h2>See Also:</h2>

<h2>Notes:</h2>
'
85
'
86
<p>This function is provided to allow for the construction of
'
87
"trees" of frames for interpreter-like environments. The macros
'
88
MATCH, MATCHING, and MATCH-CASE rely on this function, as they
'
89
immediately construct a "shared" environment.</p>
'
90
'
91
<h3>Current Implementation Note</h3>
'
92
'
93
<p>MAKE-SHARED-ENVIRONMENT relies on the LIST implementation of
'
94
environments.</p>
'
95
'
96
<p>The use of MAKE-SHARED-ENVIRONMENT in MATCHING and MATDCH-CASE is
'
97
still incomplete.</p>
