somethingblah should be defined as

sub somethingblah()
...
...
...
end sub

the end here will end the sub. but if you want to end it somewhere in the code, you can use exit sub, eg:

sub somethingblah()
...
...
if bShouldWeGoOn = False then
exit sub
end if
...
...
end sub

i hope this is what you meant, because i'm not 100% sure what you were asking...
