<I>condition-form</I>---a <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>form</I></A>; <I>evaluated</I> to produce a <I>condition</I>. <P>
|
|
<I>condition</I>---a <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>condition</I></A> <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>object</I></A> resulting from the <A REL=DEFINITION HREF="26_glo_e.htm#evaluation"><I>evaluation</I></A> of <I>condition-form</I>. <P>
|

<I>restart-form</I>---a <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>form</I></A>; <I>evaluated</I> to produce a <I>restart-list</I>. <P>

<I>restart-list</I>---a <A REL=DEFINITION HREF="26_glo_l.htm#list"><I>list</I></A> of <A REL=DEFINITION HREF="26_glo_r.htm#restart"><I>restart</I></A> <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>objects</I></A> resulting from the <A REL=DEFINITION HREF="26_glo_e.htm#evaluation"><I>evaluation</I></A> of <I>restart-form</I>. <P>

<I>forms</I>---an <A REL=DEFINITION HREF="26_glo_i.htm#implicit_progn"><I>implicit progn</I></A>; evaluated. <P>
|

<I>results</I>---the <A REL=DEFINITION HREF="26_glo_v.htm#value"><I>values</I></A> returned by <I>forms</I>. <P>

<P><B>Description:</B><P>
|
|
<P>
|
|
First, the <I>condition-form</I> and <I>restarts-form</I> are <I>evaluated</I> in normal left-to-right order; the <A REL=DEFINITION HREF="26_glo_p.htm#primary_value"><I>primary values</I></A> yielded by these <A REL=DEFINITION HREF="26_glo_e.htm#evaluation"><I>evaluations</I></A> are respectively called the <I>condition</I> and the <I>restart-list</I>. <P>
|
|
Next, the <I>forms</I> are <I>evaluated</I> in a <A REL=DEFINITION HREF="26_glo_d.htm#dynamic_environment"><I>dynamic environment</I></A> in which each <A REL=DEFINITION HREF="26_glo_r.htm#restart"><I>restart</I></A> in <I>restart-list</I> is associated with the <I>condition</I>. See <A REL=CHILD HREF="09_adbd.htm">Section 9.1.4.2.4 (Associating a Restart with a Condition)</A>. <P>

Usually this <A REL=DEFINITION HREF="26_glo_m.htm#macro"><I>macro</I></A> is not used explicitly in code, since <A REL=DEFINITION HREF="m_rst_ca.htm#restart-case"><B>restart-case</B></A> handles most of the common cases in a way that is syntactically more concise. <P>
