Note that the unary * operator treats the given address as a pointer. An expression
using this operator resolves to the value pointed to by that pointer. For example, the
expression
*Ox1234
is equal to the value at the address Ox1234, whereas
Ox1 234
is just equal to Ox1234.
Choosing Data Formats
A format is a letter or character that defines how data is to be displayed. The following
are the most commonly used formats:
Letter Format
o 1 word in octal
d 1 word in decimal
D 2 words in decimal
x 1 word in hexadecimal
X 2 words in hexadecimal
u 1 word as an unsigned integer
f 2 words in floating point
F 4 words in floating point
c 1 byte as a character
s a null terminated character string
i machine instruction
b 1 byte in octal
a the current symbolic address
A the current absolute address
n a newline
r a blank space
t a horizontal tab
A format may be used by itself or combined with other formats to present a
combination of data in different forms.
The d, o, x, and u formats may be used to display int type variables and D and X to
display long variables or 32-bit values. The f and F formats may be used to display
single- and double-precision floating-point numbers. The c format displays char type
variables and s is for arrays of char that end with a null character (null terminated
strings).
