type: Specifying the type of control data set record

Explanation: type is a required positional parameter for which you substitute the alphameric 1-character record type identification for the control data set record you want to fix or display. Table 1 shows the record types in the MCDS, BCDS, and OCDS:

Table 1. Records of the Control Data Sets
1 Character Record Type	3 or 4 Character Record Type	Record Type Name
A	MCA	MCDS alias entry record
B	MCB	BCDS data set record
C	MCC	BCDS backup version record
D	MCD	MCDS data set record
E	TCN	OCDS tape copy needed record
F	FRB	BCDS fast replication backup record
G	DGN	BCDS dump generation record
H	FRVP	BCDS fast replication volume pairs record
I	FRTV	BCDS fast replication target volume record
J	FRSV	BCDS fast replication source volume record
K	FRD	BCDS fast replication dump record
L	MCL	BCDS backup changed migrated data set record
M	MCM	BCDS move backup version record
N	VAC	MCDS JES3 volume activity count record
O	MCO	MCDS VSAM association record
P	MCP	BCDS eligible volume record
Q	ABR	BCDS aggregate group version record
R	BCR	BCDS backup control record
	BVR	BCDS backup cycle volume record subdivided into spill, unassigned, day of backup cycle (daily)
	DCR	BCDS dump control record
S	L2CR	MCDS migration level 2 control record
	MCR	MCDS management control record
	DSR	MCDS daily statistics record
	MHCR	MCDS multiple-processing-unit control record
	VSR	MCDS volume statistics record
T	TTC	OCDS tape table of contents record subdivided into spill, unassigned, day of backup cycle (daily), and migration level 2
U	MCU	MCDS user record
V	MCV	MCDS volume record
W	DCL	BCDS dump class record
X	MCT	BCDS backup volume record
Y	DVL	BCDS dump volume record
1	MC1	MCDS migration level 1 free space record
Z	MCBR	BCDS data set record for retained backup copies

Abbreviations: None.

Defaults: None.

Note: Because type is a required positional parameter, you must specify it immediately after the command name.
