Edits to the check file can be made either way. The only way to add blocks such as BEFORE FILE or BEFORE RECORD is with the editor. These should remain intact when you revise the .QES, make a new .REC or edit the .CHK either way. Can you explain in more detail or send a before/after check file? What changes were you making?

I have created the qes, rec, and chk files using 3.1. When I use add/revise on the checks menu, make changes, and then save the file, many of the previously defined labels and commands are deleted. My manual states that a check file can be created by using add/revise or the editor. Can edits to the chk file only be made using the editor?
