Need Help With String Formatting

Hey everyone, I need some help with formatting a string for use with the DoCmd.RunSQL() method. I can't figure out how the hell VB deals with escape characters for the purpse of variables inside strings. I have this line right now.

strSQL = "INSERT INTO OS (OS) VALUES(" + OS.Value + ")"


This is supposed to insert one row into the "OS" Table, in the "OS" field. In my form there is a textbox called "OS" and I'm trying to insert that value into the DB table.

Two things.
1) Yes, I know, I have a lot of things named "OS"
2) Yes, I know I don't need to use a string here, but I'm just presenting this is an abbreviated example, in my full program I do in fact need a string.
