Subject: Re[2]: quoting problem within macro loop
 
 
Giovanni,
 
Basically, SAS will _never_ resolve a macro variable referenced within single
quotes. Double quotes can be used instead of single quotes anywhere within the
SAS language. As far as I'm aware, this is the only difference between them.
 
Happy to help
Bruce

Thanks a lot Bruce for your simple, though efficient solution. I tried and
it works.
I thought that double quotes were restricted to title statements.
I'm still puzzled by the problem with single quote, but I think I
can live without it and use double quotes instead...
 
Thanks  again very much for your help.
 
-Giovanni
