VSAM PRINT command is used to print the contents of VSAM or non-VSAM datasets. Contents can be printed in various formats such as CHAR, HEX, or DUMP. We can specify our choice of format while specifying the parameters of the PRINT command. Up to 120 characters/digits are printed per line. If the record length is more than 120 characters, then the dataset is printed in blocks of 120 characters/digits per line. In a nutshell, PRINT does
PRINT {INFILE(ip-ddname[/password])|
INDATASET(ip-entryname[/password])}
*********[optional-paramters] *************
[CHARACTER|DUMP|HEX]
[FROMKEY(key)|FROMADDRESS(address)|
FROMNUMBER(number)|SKIP(number)]
[OUTFILE(ddname)]
[TOKEY(key)|TOADDRESS(address)|
TONUMBER(number)|COUNT(number)] ip-ddname – It points to the logical name of the input dataset as mentioned in the DD statement of the same step.
Example: //VSAMFL DD XXXXXX.YYYYYY.KSDSFILE,DISP=SHR
In the above statement, VSAMFL indicates ddname (i.e. logical name of Dataset)
ip-entryname – It points to the input and output data’s physical names, respectively. Ex. XXXXXX.YYYYYY.KSDSFILE.
| Parameter | Description |
| CHAR | HEX | DUMP | This parameter is used to specify the format type to be printed. Default is DUMP If CHAR is specified, it prints content in EBCDIC format. If HEX is specified, it prints content in Hexadecimal format. If DUMP is specified, it prints content in both, hexadecimal as well as character format. |
| FROMKEY (value-1) TOKEY (value-2) | Prints all records whose key field value is between value-1 and value-2 Input file must be KSDS. |
| FROMADDRESS (add-value-1) TOADDRESS (add-value-2) | Print all records whose address is between add-value-1 and add-value-2 Input file must be KSDS or ESDS. |
| FROMNUMBER (RRN-1) TONUMBER (RRN-2) | Print all records whose relative record number(RRN) value is between RRN-1 and RRN-2 Input file must be RRDS. |
| SKIP(n) | If the SKIP parameter is used, PRINT skips printing of the n number of records from the start of the file. |
| COUNT(n) | COUNT parameter is used to specify that only n number of records should be printed When the SKIP parameter is coded before the COUNT parameter, the count of the number of records to print starts right after the number of records skipped i.e. if “ SKIP(5) COUNT(10) “ is coded, then only records at row position 6 to 15 will be printed. |

// DISP=SHR In this example, all records in the VSAM file named VSAM.FILE.NAME are printed in character format using a control file named CONTROL.FILE.NAME. The CTLFILE DD statement specifies the location and access mode of the control file.
The control file is a sequential file that contains control statements to specify the output format and other options for the PRINT command. Here is an example of a control file:
OPTION HEADER ON OPTION TRAILER ON OPTION TRAILERLOC AFTER OPTION BLKSIZE 32760 OPTION LRECL 80 OPTION CHAR
The OPTION statements specify the options for the PRINT command such as the output format, the presence of header and trailer records, the location of the trailer record, the block size, and the record length. The control file allows you to customize the PRINT command options without modifying the JCL or the IDCAMS control statements.
//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
PRINT INFILE(VSAM.FILE.NAME) -
CHAR SELECT((1,5,CH,EQ,C'ABC'))
/* In this example, only the records in the VSAM file named VSAM.FILE.NAME that have the value ‘ABC’ in the first five characters are printed in character format.
The SELECT parameter specifies the selection criteria for the PRINT command using a format of (position,length,type,operator,value). You can use multiple SELECT parameters to specify complex selection criteria.
These are just a few examples of how to use the PRINT command with IDCAMS to print VSAM data. It’s important to consult the IDCAMS documentation and work with your mainframe system administrators to ensure that you are using the command correctly and effectively.
In summary, the IDCAMS PRINT command can be used to print VSAM records in different formats, including character, hexadecimal, and packed decimal. The command supports various options such as header and trailer records, sorting, and selection criteria. The PRINT command can be invoked in batch mode from JCL or interactively from the command line. Additionally, the PRINT command can use a control file to customize the output format and options. It’s important to refer to the IDCAMS documentation and consult with your mainframe system administrators to ensure that you are using the PRINT command correctly and effectively.
