Just keep a list of the aliases you used when you opened the tables, say
in an array aTables, or a collection,and when you want to close them
iterate through the list and do something like:
for i = 1 to alen(aTables, 1)
use in select(aTables[i])
endfor
If the alias is opened, it'll close it. If not, no errors or anything
will happen, it will just continue. No type checking or any further
complication required.
I do use your approach when the list of tables can vary and
tables are opened in different places, but setting up that list adds
to the complexity of the code. I usually write something like:
select clcode,clname from ccli;
where ccli in (select wonbr from cwko where wostatus in ("A","R");
order by clcode
closeforsql("ccli")
closeforsql("cwko")
