in the below example nothing;
${VAR} allows substitution without separation. i.e.
VAR=bob
${VAR}IABLE = bobIABLE
whereas
$VARIABLE is undefined
there are also some advanced uses of ${VAR} type constructs, like
${VAR:-OTHERVAR} which evals to $VAR if VAR is set and $OTHERVAR
otherwise
etc..

what is the difference between $VAR and ${VAR} apart from a whole lot
of
tricky keystrokes??
