•  To handle both NATIVE Cobol and embedded CICS STATEMENTS in the Source Program.
•  The COBOL compiler works with the INTEGRATED CICS TRANSLATOR when we use it Fromcompiler option.
•  When the compiler face CICS statements in the source program, it interfaces with the integrated CICS translator.
•  Then translator takes ACTIONS on the CICS statements and then back to the compiler, show what native language statements to generate.
•  There is no restrictions in Integrated Translator as compared to Separate Translator.
