>I'm curious Al why you added the 'in myalias' since ken's solution (which is virtually the same) works for me without it. Unless you were attempting to display the process as it occurs (which for me was not essential component to the operation.) Thanks for your input - I have a lot of places to use this new found knowledge.

The fastest and most correct way is

replace myval with int(myval) for myval < 7  in alias

The only time myval needs an alias is when you're replacing across multiple aliases joined with set relation - a technique that should be avoided.
