How to store a symbol combination?

Hello my friends
How can I store a symbol combination in the store() function?

I am not sure what you are asking. Can you give more detail on what you are trying to accomplish?

As Marc said, it would be helpful to have details on what you are trying to accomplish.

Some people try to place a digraph in a store, for example:

store(C) "d" "t" "th"

but stores aren’t intended to include digraphs, so this equivalent to

store(C) "dtth"

which isn’t what the author intended.
