Internal sort is manual sort use in cobol.
external sort is in jcl using inbuild program name called sort

ex

synatx for internal sort

sort/merge sortfile on ascending/descending
key1/key2/key3,using file1/file2/input procedure is
section-1 giving file3/file4/output procedure is section-2


nobody can write syntax more than this.it is combination.
