Does SQL allow underscores in the column name?

As above really!

I've got a table which I'm trying to insert a column into and while the column is adding just fine, any scripts I run which reference that column fail which tells me the answer is no!

Thanks for your help!

I'm a bit of an SQL noob but managed to answer my own question. After hours of testing various combinations, it would appear the software is as fault.
