Syntax of Command Elements

Many commands take an address value. An address argument value can have one of the following forms:

Decimal number	A number starting with 1-9 is a decimal number, for example 4095.
Octal number	A number starting with 0 and a digit is an octal number, for example 033.
Hex number	A number starting with 0x is a hexadecimal number, for example 0xffff8000.
Binary number	A number starting with 0b is a binary number, for example 0b0100.
Symbol	A word starting with a non-digit is looked up as a symbol in the kernel symbol table, and its address is the value; for example dk_open.
Register	A word starting with "$" is taken as a register name, and the contents of the register as of the last interrupt is used as the argument value; for example $a2.
Value and offset	A value plus or minus a number is a value, for example $a2-0x100 or dk_open+128.

Some commands accept a range of addresses. A range can be written in one of two ways:

• As value1:value2, meaning an inclusive range of addresses from value1 through value2, for example prtbuf:prtbuf+4096.

• As value1#count2, meaning a range of count2 bytes beginning at value1, for example prtbuf#4096.
