I disagree with you Paul, I like your solution best.
In fact I was about to post a response, and then saw yours, and
sent my inelegant solution to the intergalactic bitbucket in the sky.
I don't think the above is really any different than the original question
(it is easy to paste do_that(x) 10 times.)

COOL!
How about something along the lines of:
commandstrings = strarray(12)
commandstrings[0] = 'do_this()'
commandstrings[1:9] = 'do_that(x)'
commandstrings[10] = 'do_something_else()'
commandstrings[11] = 'do_something_more()'
commandstrings[12] = 'do_elsedefault()'

r = execute(commandstring[x])

NOTE: the
commandstrings[12] = 'do_elsedefault()'
takes advantage of IDLs array overrun "feature" where any x
gt 11 will call that last element (thereby reproducing the effect of the
"else" statement in the case command).

Cheers,
bob
