I don't even remember which program that I ended up using (I tried a bunch of text editors).
I just found the program, again.
It's called EditPad Lite 7.
I'm not sure what kind of regex it uses, but it's the only program that I tried that would work with the code posted above.
Also, I figured out how to do the date conversion that I was asking about, without messing other things up.
That will only find...
space letterletterletter space numbernumber space
That will replace it as...
space numbernumber space letterletterletter space
There's no chance of "Enrichm2010 ent", since it specifically requires the correct spacing, lettering, and numbering (I can't think of any logical problems, at least).
Actually, that code was used for a slightly different format (no , after the numbernumber).
The principle is the same, though.
