<h2>Description:</h2>
'
62
'
63
<p>The SUBSEQ-TEMPLATE class denotes those object that are used
'
64
to unify against a particular element of an ARRAY.</p>
'
65
'
66
<h3>Template Syntax:</h3>
'
67
'
68
<p>
'
69
<pre>
'
70
#T(<b>subseq</b> <i>start</i> <i>end</i> . <i><destructuring template lambda list></i>)
'
71
</pre>
'
72
</p>
'
73
'
74
'
75
<p>The SUBSEQ-TEMPLATE syntax is used to unify the elements of a
'
76
SEQUENCE starting from <i>start</i> and below <i>end</i>, against
'
77
the <i><destructuring template lambda list></i>.</p>
'
78
'
79
<p><i>start</i> and <i>end</i> must be supplied and must be valid
'
80
sequence indexes, i.e. most likely, FIXNUMs; however, <i>end</i> can
'
81
also be NIL, in which case the usual SUBSEQ semantics applies.</p>
'
82
'
83
'
84
'
85
<h2>Examples:</h2>
'
86
'
87
<p>
'
88
<pre>
'

cl-prompt> (setf e (unify #(0 1 42 3 4 5) #T(<b>subseq</b> 2 4 ?x ?y)))

#<ENVIRONMENT xxx>
'
91
'
92
cl-prompt> (find-variable-value '?x e)

cl-prompt> (setq e (unify #(0 1 42 3 4 5) #T(<b>subseq</b> 0 4 42 ?x)))
'
101
--> Error: UNIFICATION-FAILURE
'
102
'
103
'
104
cl-prompt> (setq e (unify "This is a string!" #T(<b>subseq</b> 4 nil &rest ?str)))
'
105
#<ENVIRONMENT xxx>

106
'
107

<h2>Exceptional Situations:</h2>
'
119
