I agree 100%. Blind mass substitution can be a disaster, esp. for short strings! I'm always careful when doing such things. Also, I don't think I ever needed this particular capability, but I know it exists, so I had to post it. 

One day at a remote lab, our experiment was done. As a lowly grad student, it was my job to make backup copies all the 9-track tapes we wrote our data to. Don't want to lose all that hard-gained data!!! We had the lab to ourselves for several days or maybe even a week or week and a half. Don't want all that long hard work to go to waste!!! 

Took about 10 min. to make a copy of each tape. So I thought I'd take the opportunity to catch up to everyone else on VMS. During each 10 min. interval I literally plowed through the DCL dictionary, and probably the User's manual and  the EDT manual, too. 

Again to all: If EDT is not up to your needs, sure, use whatever is. But those editors only get in my way. I am working on DCL scripts. Nothing terribly fancy. For this, EDT serves me well. All I am doing is sprucing up TO.COM (fixed a bug, too!) to resubmit the current version (a somewhat old one is there). And maybe check on other things.
 
My favorite thing about EDT is probably the way it does the key definitions.

Again, if anyone can find the release notes for fixing, or even the one describing the SET DEFAULT problem, please do post. (Was most likely the 6.0, 6.1, or 6.2 version of OpenVMS where the problem was described.)
