+## examinemem
+Examine memory: x /[<FMT>] ADDRESS.
+	FMT is a count followed by a format letter and a size letter.
+
+    Count number is the number of examining Size.
+    Format letter is one of o(octal), x(hex), d(decimal), u(unsigned decimal).
+    Size letter is one of b(byte), h(halfword), w(word), g(giant, 8 bytes).
+
+    ADDRESS is an expression for the memory address to examine.
+
+    Default for FMT is 8xb.  
+	For example:  x /8xb 0xc00008af38
+
+
+Aliases: x
+
 ## exit
