Thank you for your reply with apology for non-plain text mail & varous typos. After a shower and your reply, I can refine my question. As you wrote, <!--#var "english.members.test.docTest.TR"--> works OK. (docTest is DTML Document and TR is its property) But only as far as I *hard code* into every DTML Document such a line(yes there is a way to hard code such a line into every DTML Document if I have to but it seems too foolish and complicated). Is there a way to write *ONE* DTML code and use it in every DTML Document? I wrote in the root folder an one liner DTML method 'isTRed' which is <!--#var "'english.'+ _.string.join( _.string.split(URL0, '/')[4:], '.')+'.TR'" --> It gives the string english.members.test.docTest.TR when called in the DTML Document /korean/members/test/docTest as <!--#var isTRed-->. But <!--#var "isTRed" --> gives the source of isTRed method. And <!--#var "_[isTRed]"--> gives attribute error. <!--#var "_['isTRed']"--> gives the string english.members.test.docTest.TR as might be expected. Please don't laugh at my silliness, : (. Any revelation? TIA LEE Kwan Soo.
