00 (X'00')	8	TEPOID	Control block identifier
08 (X'08')	4	TEPOLEN	Length of parameter list
12 (X'0C')	1	TEPOVER	Version of parameter list (1)
13 (X'0D')	3		Reserved
16 (X'10')	1	TEPOFLAG1	Flags

18 (X'12')	2	TEPOSAFRC	SAF/RACF return code
20 (X'14')	2	TEPOSAFRS	SAF/RACF reason code
22 (X'16')	44	TEPODSNF1	File 1 dsname to be returned by Volume Mount Exit and Volume Security Function. Used by O/C/EOV to authorize access to the first file on a volume when TAPEAUTHF1=YES is set.
66 (X'42')	2	TEPODS1FS	File 1 data set sequence number; corresponds to the JCL LABEL keyword data set sequence number.
