Allocating Data Sets
If
you enter the name of a data set that does not exist, the Allocate
Data Set pop-up window is displayed, providing an interface by which
you can allocate it.
Table 32. Allocate Data Set Pop-Up
Command ===>
This data set does not exist:
Specify allocation parameters below and press ENTER to allocate it.
Type CAN or CANCEL or press PF3 to cancel the allocation.
Unit.............. ===>
Space Units....... ===> (C=Cylinders, T=Tracks, B=Blocks)
Primary Quantity.. ===> (in above units)
Secondary Quantity ===> (in above units)
Directory Blocks.. ===> (0 for a sequential data set)
Record Format..... ===>
Record Length..... ===>
Block Size........ ===> |
If you press Enter, all input fields will
be validated. If any errors are detected during input validation,
the window will be redisplayed with an error message. If there are
no errors, then the data set will be allocated with the specified parameters
and you return to the previous panel.
If you press PF3, all input fields will
be ignored and you return to the previous panel. The data set will
not be allocated.
The fields on the window are:
- Unit
- Enter the device type to which the data set should be allocated,
for example, SYSDA.
- Space Units
- Enter C to express the size of the data set in cylinders, T to express the size in tracks, or B to express the size in blocks.
- Primary Quantity
- Enter the primary space allocation for the data set, in the
specified Space Units.
- Secondary Quantity
- Enter the secondary space allocation for the data set, in
the specified Space Units.
- Directory Blocks
- Enter the number of directory blocks for the data set, which
will be a PDS as a result. Enter 0 to allocate a sequential data set.
- Record Format
- This field displays the record format required for the type
of data set being allocated. You cannot change this value.
- Record Length
- This field displays the record length required for the type
of data set being allocated. You cannot change this value.
- Block Size
- Enter the block size for the data set. For data sets with
a fixed record format, this must be a multiple of the record length.
For data sets with a variable record format, this must be at least
four greater than the record length. For data sets with an undefined
record format, this must be a value greater than zero.
