<dt><a name="wait"><code>(wait ['cnt] . prg) -> any</code></a>
<dd>Waits for a condition. While the result of the execution of <code>prg</code>
is <code>NIL</code>, a <code>select</code> system call is executed for all file
descriptors and timers in the <code>VAL</code> of the global variable <code><a
href="refR.html#*Run">*Run</a></code>. When <code>cnt</code> is
non-<code>NIL</code>, the waiting time is limited to <code>cnt</code>
milliseconds. Returns the result of <code>prg</code>. See also <code><a

<dt><a name="when"><code>(when 'any . prg) -> any</code></a>
<dd>Conditional execution: When the condition <code>any</code> evaluates to
non-<code>NIL</code>, <code>prg</code> is executed and the result is returned.
Otherwise <code>NIL</code> is returned. See also <code><a
href="refU.html#unless">unless</a></code>.

<dt><a name="while"><code>(while 'any . prg) -> any</code></a>
<dd>Conditional loop: While the condition <code>any</code> evaluates to
non-<code>NIL</code>, <code>prg</code> is repeatedly executed. If
<code>prg</code> is never executed, <code>NIL</code> is returned. Otherwise the
result of <code>prg</code> is returned. See also <code><a

<dt><a name="wipe"><code>(wipe 'sym|lst) -> sym|lst</code></a>
<dd>Clears the <code>VAL</code> and the property list of <code>sym</code>, or of
all symbols in the list <code>lst</code>. When a symbol is an external symbol,
its state is also set to "not loaded". Does nothing when <code>sym</code> is an
external symbol that has been modified or deleted ("dirty").

<dt><a name="with"><code>(with 'sym . prg) -> any</code></a>
<dd>Saves the current object <code>This</code> and sets it to the new value
<code>sym</code>. Then <code>prg</code> is executed, and <code>This</code> is
restored to its previous value. The return value is the result of
<code>prg</code>. Used typically to access the local data of <code>sym</code> in
the same manner as inside a method body. <code>prg</code> is not executed (and
<code>NIL</code> is returned) when <code>sym</code> is <code>NIL</code>.
<code>(with 'X . prg)</code> is equivalent to <code>(let? This 'X . prg)</code>.
<pre><code>

<dt><a name="wrap"><code>(wrap 'cnt 'lst) -> sym</code></a>
<dd>Returns a transient symbol with all characters in <code>lst</code> <code><a

<code>cnt</code>. See also <code><a href="refT.html#tab">tab</a></code>,
