Front 25

The SPACE parmaeter is coded for non-VSAM data sets to inform the system the amount of primary and secondary space to be allocated on a direct-access storage device (DASD).

Back 25

The SPACe parameter is used ONLY with a new data set, i.e., STATUS=NEW

Front 26

SPACE contains two positional subparameters -- Unit of measure, amount of space, and release.

Back 26

SPACE=(unit of measure,amount of space,release)

Front 27

One track on 3390 DASD has the capacity to contain 56,664 characters or bytes of data.

Back 27

One cylinder represents 15 tracks of data on a 3390 device.

Front 28

SPACE coding Rule 1.
Must be enought space on one volume to satisfy the primary quantity. A request for a specific volume when there is not enought space will cause the job step to abend.

Back 28

SPACE coding Rule 2.
When requesting space in units of blocks, teh average block length may not exceed 65,335 bytes.

Front 29

SPACE coding Rule 3.
When creating a PDS (partioned data set), you must request space for a directory.

Back 29

SPACE coding Rule 4.
Code a comaa if secondary allocation is omitted and directory allocation is requested.

Front 30

SPACE coding Rule 5.
When requesting secondary allocation, the system will attempt to allocate space in contiguous tracks or cylinders. If continguos space is not available, the system will attempt to allocate space in up to five non-contiguous extents.

Back 30

SPACE coding Rule 6.
Secondary allocaiton or extents can be invoked up to 16 times based on availability.

Front 46

What is the last enterable column on a JCL statement?

Back 46

Column 71. Sometimes column 72 is used for continuation characters.

Front 47

What are the four basic JCL statements?

Back 47

1. JOB
2. EXEC
3. DD
4. Comments

Front 48

Keyword Parameter: MSGCLASS

Back 48

Values can be A through Z or 0 through 9

Front 49

MSGCLASS (Keyword Parameter)

Back 49

System message and output data sets can be routed to the same output class.
Code SYSOUT=* on all DD statements for the SYSOUT data sets that should default to the MSGCLASS output class of the job.

Front 50

MSGCLASS (Keyword Parameter)

Back 50

Examples:

//QNMDPRNT JOB 00089600730JPGBOC,GRECO, MSGCLASS=A

Front 51

What character is used on the delimiter between parameters?

Back 51

The comma.

Front 52

MSGCLASS (Keyword Parameter)

Back 52

Specifies the output class to which system message and JCL statements are written.

Front 53

What are the two types of parameters found on JCL statements?

Back 53

Keyword and Positional

Front 54

Which is coded first, keyword or positional parameters?

Back 54

Positional parameters are coded before keyword parameters.

Front 55

How many DD Cards are needed to successfully run a job?

Back 55

You must have at least 1 DD card to successfully run a job.
