Cursor placement

Greetings,  

What methods are available to position a cursor on a screen to begin writing as not to disrupt other areas of the screen?  I have used ?# , ie: ?5 but this is destructive from the let to character 5.  I would like to enter a command that will position at row,col and then start writing?  Can I create a window in a window type display to write text and then when done viewing, remove it?

Please advise,

Thanks in advance for everyone's time.
