The x I can't remember off-hand, but I think is a placeholder for variable input. You might have to experiment with viewing the disassembly of a function such as MOV or ADD, or look at the source code of the utility that creates the inc files. As for the numbers, they are octal (historical reasons, I think mostly because there were only 8 general-purpose registers to deal with).
The only time I personally modified this file was some time go to reorder the MOV commands in an attempt to get the assembler to use a shorter byte sequence for small negative numbers being stored in 64-bit locations.
