the value in $1 is not that retrieved by the rule dbname. What
happens is that in that rule, the value of $1 is not "$$ of dbname
rule" but $1 + $2 , that is the two strings "dbname tablelist"
concatenated.
In other words, in the passage from one rule to another, the value
of dbname is lost.
Any advice?
