%let and html path

deleted_user — Wed, 03 Mar 2010 18:23:55 GMT

I'm trying to use a %let statement to store a html path.
However, it doesn't seem to be working:

%let path=%str(http://domapp.com/Applications/AS/CZ/03de670ff5/$FILE);
html='href="&path./summary_bu.htm"';

Any suggestions?
Thank you.

hi ... macro variables only resolve when inside double quotes ...
[pre]
%let path=%str(http://domapp.com/Applications/AS/CZ/03de670ff5/$FILE);
data _null_;
length html $80;
html = 'href="&path./summary_bu.htm"';
put 'HTML: ' html;
html = "href='&path./summary_bu.htm'";
put 'HTML: ' html;
html = "href=""&path./summary_bu.htm""";
put 'HTML: ' html;
run;

the LOG ...
HTML: href="&path./summary_bu.htm"
HTML: href='http://domapp.com/Applications/AS/CZ/03de670ff5/$FILE/summary_bu.htm'
HTML: href="http://domapp.com/Applications/AS/CZ/03de670ff5/$FILE/summary_bu.htm"
[/pre]

An aside: Mike's second example doesn't look like it should work, e.g. one wouldn't expect the SAS Macro Facility to resolve the &path variable inside of the single quotes. But since these lie within double quotes, the macro facility sees the single quotes as plain-old characters and not single quotes and DOES resolve the &path variable within.

html = "href='&path./summary_bu.htm'";
put 'HTML: ' html;

(snip snip)

HTML: href='http://domapp.com/Applications/AS/CZ/03de670ff5/$FILE/summary_bu.htm'
