  Text:         Recursive non MF PERFORM is illegal
 
  Severity:     Fatal
 
  Explanation:  You have tried full recursion of a PERFORM statement
                in a program that was submitted to your COBOL system
                with the OSVS parameter of the PERFORM-TYPE directive
                specified.  That is, you have attempted to end two
                PERFORMs with the same return address.
 
  Resolution:   You should either resubmit your program to your COBOL
                system with a parameter other than OSVS specified for
                the PERFORM-TYPE directive, or recode your program so
                that each PERFORM has its own unique return address
                before you resubmit it to your COBOL system with the
                MF parameter of the PERFORM-TYPE directive specified.
