Witness:


. loc Y "Balance (\$Bn's)"

. mac li _Y
_Y:             Balance ($Bn's)


which shows that the local macro Y does indeed contain "Balance  
($Bn's)"; the problem is that after Y has been expanded in your  
display command, the $B is then replaced by the contents of the  
global macro B (which in this case is nothing).  To avoid this  
subsequent expansion, use


. di "`macval(Y)'"
Balance ($Bn's)


instead.
