In `adb` displaying addresses can be achieved with "symbol,200?ia" or 
"address,200?ia".   This will print 200 lines of disassembly with addresses 
starting at symbol.  The '?' means to display from the text (code) section, 
any address not found in the text section will display "Text address not found" 
messages.  In `sdb` this would be done by "symbol?200i" or "address:?200i".
