Confirmed for Vim 6.3. Seems like some kind of octal increment/decrement confusion. However, I think Hari meant to say Normal mode instead of Insert mode. Vim thinks that it's an octal number because of 0 followed by [0-9]\+ (yes, it should be [0-7]\+). But when it encounters [8-9]\+\d*$, it takes 0 as the octal number itself, and not as the octal indicator (as "0x" is the hex indicator). This is evident with: 08123 Placing the cursor on any of the 5 digits and hitting Ctrl-x produces: 0377777777778123 Some may say it is correct operation ;) except for the fact that Vim confuses the indicator for the number itself. Hence, performing the same on: 008123 also produces: 0377777777778123 In this case, the good 0 is decremented to -1 in octal. Of course, the fix for this behavior on any Vim is :set nrformats-=octal See ":help 'nrformats'". HTH :) -- Gerald
