Hmmm...

One way to do that would be to store the old combo$ before you add something.  For example:

#oldcombo$=combo$
#combo$=combo$+a$

Then when you want to subtract the last one:

#combo$=oldcombo$

But that will only allow you to back up once.

Hmmm, now that I think of it, a$ is only one letter, right?  You could take apart the varaible with #CharAt and reconstruct it without the last letter.  For example, when adding:

#combo$=combo$+a$
#combolength!=combolength!+1

Now when taking the last letter off:

#newcombo$=""
#for(i!=1;i!<combolength!;i!=i!+1)
{
  #charat(combo$,i!,a$) *puts the letter in position i! into a$
  #newcombo$=newcombo$+a$
}
#combo$=newcombo$

That'll copy everything before the last letter into newcombo$, which then replaces what's in combo$.
