godaddy domain forwarding - will it affect other A records?

view story

http://serverfault.com – I need to forward the default URL of my site (such as mydomain.com or www.mydomain.com) but keep my other A record assignments (points to other server IPs). Godaddy has a domain forwarding function in the domain management, if I use that forward my domain from mydomain.com to myotherdomain.com will my other dns A records be affected? Such as sub.mydomain.com, sub2.mydomain.com Thanks! (HowTos)
