editing an instance variable in an OrderedCollection

if i have an ordered collection of say albums...

and the albums have a 'desc' instance variable..

and i decide i want to change 'desc' from 'this is a bad album' to
'this is a good album' on the 7th element in the list, how would i
phrase that?

i am kicking around:

Album repository at: 7 desc: 'this is a good album'

but i don't think the evaluation order is correct..

any ideas?

thanks!

You just need to use parentheses, like so:

(Album repository at: 7) desc: 'this is a good album'

BTW, it is better to use full words for your method and variable names
-- they are much easier to guess.

I don't know about the context where you want to use this, but maybe
it is a good idea to separate it into two statements:

album := Album repository at: 7.
album description: 'this is a good album'.

yes.. i first used description, but i saw that it was overriding
another method, so i thought i might play it safe..

that was what i initially thought.. but i wasn't sure it it was saving
me anything by putting them together...

thanks!
