(Warning: novice user ahead...)  I am using the following macros in order
to typeset code listings (taken from WEB book, p. 243):

\chardef\other=12
\def\ttverbatim{\begingroup
	\catcode`\|=\other
	\catcode`\\=\other
	\catcode`\{=\other
	\catcode`\}=\other
	\catcode`\$=\other
	\catcode`\&=\other
	\catcode`\#=\other
	\catcode`\%=\other
	\catcode`\~=\other
	\catcode`\_=\other
	\catcode`\^=\other
	\obeyspaces \obeylines \tt}
{\obeyspaces\global\let =\ } % from TeXbook, p. 381
\outer\def\verbatimcode{\par\ttverbatim\leftskip=0em\parskip=0pt
	\baselineskip=12pt\ttfinishcode}
{\catcode`\|=0 |catcode`|\=\other % | is temporary escape character
	|obeylines % end of line is active
	|gdef|ttfinishcode#1^^M#2\endverbatimcode{#1#2|endgroup}}

These macros generally work well except that blank lines are discarded.
Can anyone suggest what to change to make blank lines appear as intended?

Thanks in advance, please reply directly.
