9.5. ORACLE RDBMS: .SYM-FILES
We will add red lines to divide the block:
Figure 9.25:Binary block patternsHiew, like almost any other hexadecimal editor, shows 16 bytes per line. So the pattern is clearly visible:
there are 4 32-bit values per line.
The pattern is visually visible because some values here (till address0x104) are always in0x1000xxxx
form, started with 0x10 and zero bytes.
Other values (starting at0x108) are in0x0000xxxxform, so always started with two zero bytes.
Let’s dump the block as an array of 32-bit values:
