Problem conclusion

• The label should ideally be used only when CONTINUE MENU is used
  in 4GL program. As a fix, I have introduced a new variable that
  will check if CONTINUE MENU keywords is reached, and the
  variable is set to 1. This value is used to generate the label
  in the .ec file, and then reset again. I have tested this fix
  for using many CONTINUE MENUS statements in 4GL application.
  Fixed in 4GL 7.50.xC6.
