The <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>function</I></A> <A REL=DEFINITION HREF="#disassemble"><B>disassemble</B></A> is a debugging aid that composes symbolic instructions or expressions in some <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A> language which represent the code used to produce the <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>function</I></A> which is or is named by the argument <I>fn</I>. The result is displayed to <A REL=DEFINITION HREF="26_glo_s.htm#standard_output"><I>standard output</I></A> in an <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A> format. <P>
