Or, you can use [subst].

What, use AOLserver to build web applications? :-)

That at least eliminates the escaping of double-quotes issue. There's
even more ways of refactoring your example to condense it further:
switch $vlCountryCode {
DE { set tag {<a
href="http://www.aol.de/action_templates/globalhelp_1.jsp?cid=1041541"; target="top">} }
FR { set tag {<a href="http://aolaide.aol.fr/version4/topic/theme6.htm";
target="top">} }
default { set tag {<a
href="javascript:pop=prntPack('help/help.adp',530,500);">} }
}
ns_adp_puts [subst {<td background="$imageDir/hdr_bg.gif" valign="top"
align="right">$tag<img src="$imageDir/btn_helptop.gif" width=$img2w
height=$img2h border=0 alt="$str6"></a></td>}]

Matter of preference. I, personally, prefer the second refactoring I
provided above.

Use a better text editor? :-)
