24.1.1 Loading</H2> <P>

To <A REL=DEFINITION HREF="f_load.htm#load"><B>load</B></A> a <A REL=DEFINITION HREF="26_glo_f.htm#file"><I>file</I></A> is to treat its contents as <A REL=DEFINITION HREF="26_glo_c.htm#code"><I>code</I></A> and <A REL=DEFINITION HREF="26_glo_e.htm#execute"><I>execute</I></A> that <A REL=DEFINITION HREF="26_glo_c.htm#code"><I>code</I></A>. The <A REL=DEFINITION HREF="26_glo_f.htm#file"><I>file</I></A> may contain <A REL=DEFINITION HREF="26_glo_s.htm#source_code"><I>source code</I></A> or <A REL=DEFINITION HREF="26_glo_c.htm#compiled_code"><I>compiled code</I></A>. <P>

A <A REL=DEFINITION HREF="26_glo_f.htm#file"><I>file</I></A> containing <A REL=DEFINITION HREF="26_glo_s.htm#source_code"><I>source code</I></A> is called a <A REL=DEFINITION HREF="26_glo_s.htm#source_file"><I>source file</I></A>. <I>Loading</I> a <A REL=DEFINITION HREF="26_glo_s.htm#source_file"><I>source file</I></A> is accomplished essentially by sequentially <I>reading</I>[2] the <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>forms</I></A> in the file, <I>evaluating</I> each immediately after it is <A REL=DEFINITION HREF="26_glo_r.htm#read"><I>read</I></A>. <P>

A <A REL=DEFINITION HREF="26_glo_f.htm#file"><I>file</I></A> containing <A REL=DEFINITION HREF="26_glo_c.htm#compiled_code"><I>compiled code</I></A> is called a <A REL=DEFINITION HREF="26_glo_c.htm#compiled_file"><I>compiled file</I></A>. <I>Loading</I> a <A REL=DEFINITION HREF="26_glo_c.htm#compiled_file"><I>compiled file</I></A> is similar to <I>loading</I> a <A REL=DEFINITION HREF="26_glo_s.htm#source_file"><I>source file</I></A>, except that the <A REL=DEFINITION HREF="26_glo_f.htm#file"><I>file</I></A> does not contain text but rather an <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A> representation of pre-digested <A REL=DEFINITION HREF="26_glo_e.htm#expression"><I>expressions</I></A> created by the <A REL=DEFINITION HREF="26_glo_c.htm#compiler"><I>compiler</I></A>. Often, a <A REL=DEFINITION HREF="26_glo_c.htm#compiled_file"><I>compiled file</I></A> can be <I>loaded</I> more quickly than a <A REL=DEFINITION HREF="26_glo_s.htm#source_file"><I>source file</I></A>. See <A REL=CHILD HREF="03_b.htm">Section 3.2 (Compilation)</A>. <P>

The way in which a <A REL=DEFINITION HREF="26_glo_s.htm#source_file"><I>source file</I></A> is distinguished from a <A REL=DEFINITION HREF="26_glo_c.htm#compiled_file"><I>compiled file</I></A> is <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A>. <P>
