Hi,

This issue has been in there since forever, catching many of us (myself 
included) off-guard at times.  For now, the solution is to just 
concatenate strings in variable assignment expressions using the "+" 
operator:

$var(uriOLD) = "<" + $var(oldstr) + "batty.com;user=phone>";

As for when or if this is going to be addressed... is subject to a longer discussion...

Best regards,
