DMS messages during label processing

During label processing, DMS may react with the following messages to conflicts detected during label checking:

DMS0DA1  WRONG VSN ON DEVICE (&00). MOUNT VSN (&01) FOR FILE (&02) VSEQ '(&03)'. REPLY 
           (0=EXIT; 1=RETRY; 2=DISPLAY LABEL; I=IGNORE)
DMS0DA2  NO VOL1/HDR ON DEVICE (&00). MOUNT VSN (&01) FOR FILE (&02) VSEQ '(&03)'. REPLY 
           (0=EXIT; 1=RETRY; 2=DISPLAY LABEL)
DMS0DA3  WRONG OVERWRITE ACCESS: VSN '(&00)' FOR FILE '(&01)' VSEQ '(&02)'. REPLY (0=EXIT; 
           1=RETRY; 2=DISPLAY LABEL; I=IGNORE)
DMS0DA5 WRONG FILE IDENTIFICATION: VSN '(&00)' FOR FILE '(&01)' VSEQ '(&02)'. REPLY (0=EXIT; 
           1=RETRY; 2=DISPLAY LABEL; I=IGNORE)
DMS0DD6  WRONG FILE SET IDENTIFIER ON VSN '(&00)' FOR FILE '(&01)' VSEQ '(&02)'. REPLY 
           (0=EXIT; 1=RETRY; 2=DISPLAY LABEL; I=IGNORE)
DMS0DD7  ILLEGAL ACCESS BY FOREIGN USER: VSN '(&00)' FOR FILE '(&01)' VSEQ '(&02)'. REPLY 
           (0=EXIT; 1=RETRY)
DMS0DD8  STD FILE LABELS NOT FOUND ON VSN '(&00)' FOR FILE '(&01)' VSEQ '(&02)'. REPLY 
           (0=EXIT; 1=RETRY; 2=DISPLAY LABEL)
DMS0DF6  INPUT TAPE WITH VSN (&00) HAS STD LABELS; BUT SHOULD BE TREATED AS NSTD OR NO. 
           REPLY (0=EXIT; C=CONTINUE)
DMS0DFB  VSN '(&03)' ON '(&00)'FOR FILE '(&01)' VSEQ '(&02)' OK? REPLY (TSN.0=ERROR EXIT; 
           TSN.1=RETRY; TSN.2'XXXXXX'=NEW VSN; TSN.=ACCEPT)

The texts in the messages have the following meanings:

EXIT	if available, the exit routine in the program is activated and can intercept the error and terminate the program normally.
RETRY	The label check is repeated (see section "Repeat label checking (RETRY)").
DISPLAY LABEL	The contents of the HDR label being checked are sent via system file SYSOUT to the screen or, for batch processing, written into the SYSOUT file.
NEW VSN	After a change of tape, label checking is to be repeated for the new tape (see section "Repeat label checking (RETRY)").
IGNORE	Depending on the TAPE-ACCESS authorization and the value of the SECLEV operand in the FILE/FCB macro or the PROTECTION-LEVEL operand in the ADD-FILE-LINK command, the error can be ignored and program execution can be continued.
TSN	The task sequence number of the job for which label checking was executed.
VSN	The volume serial number of the tape on which label checking was executed or the VSN of the next tape to be mounted.
