<H1>How about an example for <TT>output</TT>?</H1>
<P>Here is a simple example to demonstrate how <A HREF=output.html><TT>output</TT></A>, <A HREF=pushoutput.html><TT>push_output</TT></A>, and
<A HREF=popoutput.html><TT>pop_output</TT></A> work:</P>
<P>
<PRE>output "Hello, world!\n"; # (Written to STDOUT by default)
push_output('nul'); # Push 'nul' ahead of STDOUT
output "Hello, again!\n"; # (Discarded)
push_output('file','foo.out'); # Push file 'foo.out' ahead of 'nul'
output "Hello, again!\n"; # (Written to the file 'foo.out')
pop_output; # Pop 'foo.out' and revert to 'nul'
output "Hello, again!\n"; # (Discarded)
push_output('string'); # Push 'string' ahead of 'nul'
output "Hello, "; # (Written to the string)
output "again!\n"; # (Also written to the string)
# Pop the string "Hello, again!\n"
$foo = pop_output; # and revert to 'nul'
output "Hello, again!\n"; # (Discarded)
pop_output; # Pop 'nul' and revert to STDOUT
output "Hello, at last!\n"; # (Written to STDOUT)</PRE>
