[RESOLVED] .htaccess RewriteRule

[zzz]

I know basics of how to specify different format for my rewrites done via .htaccess
For example:

RewriteRule ^([A-Z]{3})$ mypage.php?var=$1 [L]

if the url looks like this:

http://mydomain.com/ABC

I can open mypage.php and use the var = ABC

Is there a way to specify a range of chars, say if 2-10 and do the same redirect? BTW it could be a mixed alpha and numeric chars...

http://mydomain.com/abc234klm
