Save Commands Typed To Use later

I'm looking for something that is like this:

$ startmem
$ command1
$ command2
$ command3
$ endmem

Later, I want to call it like this: mem, which executes the commands.
To clear, just use startmem again. Is there a way to to this?

You could do this:

startmem () { eval "mem() { $(sed '/^endmem/Q'); }"; }

That will take your input, up to but not including the "endmem" line, and generate a "mem" function.

If you want it to persist, then you have no choice but to write it to disk

startmem () { sed '/^endmem/Q' > ~/.mem_commands; }
mem ()      { source ~/.mem_commands; }

But at this point, why don't you just create ~/bin/mem, add ~/bin to your PATH, and just edit the mem file when you want to change it.
