// Dialog allows the user to enter
//  - A starting address
//  - An ending address
//
//  this can be in the form
//            functiom/method name
//            variable address (ie &Var, str)
//            Memory address 0x8040abc
//
//  When disassembling and you enter a method name without an
//  ending address then the whole method is disassembled.
//  No data means disassemble the method we're curently in.(from the
//  start of the method)
//
// click ok buton to send the request to jdb
// the output is returned (some time later) in the raw data slot
// and displayed as is, so it's rather crude, but it works!
