6.1.7.1 Control Transfer Clauses</H2> <P>
|

The <TT>named</TT> construct establishes a name for an <A REL=DEFINITION HREF="26_glo_i.htm#implicit_block"><I>implicit block</I></A> surrounding the entire <A REL=DEFINITION HREF="m_loop.htm#loop"><B>loop</B></A> so that the <A REL=DEFINITION HREF="s_ret_fr.htm#return-from"><B>return-from</B></A> <A REL=DEFINITION HREF="26_glo_s.htm#special_operator"><I>special operator</I></A> can be used to return values from or to exit <A REL=DEFINITION HREF="m_loop.htm#loop"><B>loop</B></A>. Only one name per <A REL=DEFINITION HREF="m_loop.htm#loop"><B>loop</B></A> <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>form</I></A> can be assigned. If used, the <TT>named</TT> construct must be the first clause in the loop expression. <P>
|
||
|
|
The <TT>return</TT> construct takes one <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>form</I></A>. Any <A REL=DEFINITION HREF="26_glo_v.htm#value"><I>values</I></A> returned by the <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>form</I></A> are immediately returned by the <A REL=DEFINITION HREF="m_loop.htm#loop"><B>loop</B></A> form. This construct is similar to the <A REL=DEFINITION HREF="s_ret_fr.htm#return-from"><B>return-from</B></A> <A REL=DEFINITION HREF="26_glo_s.htm#special_operator"><I>special operator</I></A> and the <A REL=DEFINITION HREF="m_return.htm#return"><B>return</B></A> <A REL=DEFINITION HREF="26_glo_m.htm#macro"><I>macro</I></A>. The <TT>return</TT> construct does not execute any <TT>finally</TT> clause that the <A REL=DEFINITION HREF="m_loop.htm#loop"><B>loop</B></A> <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>form</I></A> is given. <P>
