Flag:

 

 

 

  • If UTARGETs (USER targets) are defined, X'80' bit

 

 

 

  • If NTARGETs (NET targets) are defined, X'40' bit

 

 

 

  • If HTARGETs (host targets) are defined, X'20' bit

    – =0 if user time is defined (0 is the default)
    – =1 if host time is defined

 

 

 

  • If type C entry, X'10' bit, PIU distribution ranges follow

 

 

 

  • If type I entry:

    – X'80' bit, interval record
    – X'40' bit, final record for ended session
