Thanks Eric.
I wasn't looking for anything in particular. Seeing the E-M-S 3-line notation reminded me what a pain those invisible delimiters for raising/lowering indexing scripts can be. Which was what made me reach out to bzg. (I won't be able to reply from this address as it expires in the next few days. The T&C when renewing the address goes to a "nothing" page in transition, so I let it go. I should resurface from sdf.org ) -- VL
