 From Sun's java command line reference (keep in mind: this is a 
'non-standard' option, and is only guaranteed for Java versions ~ 1.1 -
6):

-Xmxn
     Specify the maximum size, in bytes, of the memory allocation pool. 
This value must a multiple of 1024 greater than 2MB. Append the letter k 
or K to indicate kilobytes, or m or M to indicate megabytes.
  (e.g. -Xmx40m)

This is the URL for the Java 6 version of the command line:
http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html#nonstandard

and the earlier versions can be obtained by changing the javase/6/ to 
j2se/1.{5,4.2,?}/
