Multiple offenders

[Richmond]

Oh Dear, its that time of the month again.

Yes it is; Richmond's error trawl......

read "SDLC" and other acronyms that cover up
incredibly time-consuming exercises.

So, here I am merrily going through some 50 objects changing 57620 to 57618
and 57768 to 57769; very, very tedious indeed.

Of course life would be about 1,000,000 times easier if each object had 
the same code;
but they don't; just the lines containing those number that need to be 
altered.

Has anybody any bright ideas how this might be done semi-automatically?
