You can use the inline-memory format specifiers:
-- inline-memory format specifiers. These take the form
address_expr, <format specifier> format specifiers: (note that the names of these specifiers were borrowed from WinDBG)
db : display byte values along with ASCII characters
dc : double-word values and ASCII characters
dd : double-word values
dD : double-precision floating-point numbers
df : single-precision floating-point numbers
dq : quad-word values
dW : word values and ASCII characters
dw : word values
dyb : binary values and byte values
dyd : binary values and double-word values
/c : used to specify the number of columns (e.g., /c16). If not specified, then a suitable default for the format specifier is used.
/n : used to specify the number of objects (bytes, words, double-words, quad-words, floats, or doubles); e.g, /n12. Cannot be used if ending_address_expr is given.
ending_address_expr : any expression that can be evaluated to an address. Cannot be used at the same time as the '/n' option.
For example
arr, db /c16 arr+64will display 4 lines of 16 values in arr :

The README.txt supplied with the debugger has more format specifiers in it.
