In HTML,
these two chars work the same

     "    '     dbl single
if you start a string with a single quote, it continues until the next  
single quote
if you start a string with a dbl quote, it continues until the next  
dbl quote
  so  var = 'a phrase containing a " char is kept intact'
          without escaping or the  "  entity

so use the double quote for Rev and the single quote for HTML code

-A-  Without using merge() function
get empty
get IT & "<a href='http://" & fld link && "target='_blank' > & fld  
link & "</a>"
get IT & "<br/></br/>"
put IT after tData

---- the output is valid code and a clickable link
<a href='http://google.com' target='_blank' >google.com</a><br/><br/>

-B-  using the merge function
put merge( \
       "<a href='http://[[fld link]]' target='_blank' >[[fld link]]</ 
a><br/><br/> " \
       ) after tData

---- the output is valid code and a clickable link
<a href='http://google.com' target='_blank' >google.com</a><br/><br/>
