I believe there were probably exactly 456 (plus or minus) items in the "LONG SEQUENCE OF TWO CHAR QUOTED NUMBER LETTER COMBINATIONS", so yeah that's the way they stepped through them up to 456. The first few terms are: "1e","3o","4d","46","3l","4c"
I was thinking the other variable names may have been a clue to the writer, but zxc and asdg are basically keyboard neighbors. Personally, I'm a UNIX C programmer (from before there was a C++) and Windows and JS, as similar as it is, are not my forte.
As far as coming back, so far so good. I was afraid they may have hidden a cron job to reset them every night at the same time or a random time (how I would have done it :), but nothing so far.
