Hmm. do you mean I can use any character as the delimiter? How does
/bin/ed know that suddenly ! is the seperator rather than the more
usual /?

It's more a case AFAIK that /bin/ed uses the first character after the
command as the string delimiter - thus you can use any character you
like, though I would recommend sticking to the symbols (eg !%:=+ etc).

Correct, and good idea.

[It seems that the slash (/) character is used in examples, and most
often, for some dim dark historic reason (like loop counters are often
i, j, ..., n which AFAIK comes from [original] Fortran where you had to
use an integer variable for a loop variable and by default any variable
starting with one of the 6 letters I, J, ..., N is an integer).]

That's exactly backwards. Fortran reserved those letters for denoting
default integer types because those letters had always been used in
mathematics for the role of index variables.
