Answer / vampire
Internal sort is manual sort use in cobol.
external sort is in jcl using inbuild program name called sort
ex
//step1 exec pgm=sort
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.
