    External sort is performed by SORT pgm. Internal sort gives you data handling flexibility and it takes less secondary memory. For huge Volume of files it's better to use internal sort else large amount of space will be required in external sort. any comments...?

    internal sort done by cobol & external sort dine by jcl.
    the syntax for internal sort is
    sort file3 on a/d key key-name using i/p-filename giving o/p-filename

    external sort= jcl will be the good option in case of live scenario as you can use various sort condition to save the CPU time in Production.
