START with an address was useful for writing stand-alone code, which can be IPLed by preceding it with 3CARD LOADER (which seems to have grown to 5 cards since I used it in the 1970s).
My company decided to get rid of their card punch and reader but stand-alone dump/restore at the time still needed control card input, so I wrote a little stand-alone full screen editor for our 4331 console which could be IPLed from tape and write up to a screenful of control card images to another tape to be used as input. Fortunately, the stand-alone dump/restore program acquired a capability to take control information from the console soon afterwards, which was a much simpler solution.
