Field Descriptions
Exclusion
Use the Exclusion field to specify the exclusion mode of the physical file. The exclusion
mode determines the circumstances under which other processes can access the file.
The field options are:
For more information on exclusion modes, see the ENSCRIBE Programmer’s Guide.
Access
Use the Access field to specify the access mode of the physical file. The access mode
determines the file operations that processes can perform on the file. The field options
are:
For more information on access modes, see the ENSCRIBE Programmer’s Guide.
Prim Extent
Use the Prim Extent field to specify the size of the primary extent allocated to the
physical file. This file-creation attribute applies only when the program referring to the
logical file creates the physical file.
To specify the primary extent size, enter an integer in the range 1 through 65534.
Sec Extent
Use the Sec Extent field to specify the size of the secondary extents allocated to the
physical file. Secondary extents are allocated after the primary extent. This file-creation
attribute applies only when the program referring to the logical file creates the physical
file.
To specify the secondary extent size, enter an integer in the range 1 through 65534.
File Code
Use the File Code field to assign a file code to the physical file. This file-creation
attribute applies only when the program referring to the logical file creates the physical
file.
To specify the file code, enter an integer in the range 0 through 65534. For a list of
reserved file codes, see the File Utility Program (FUP) Reference Manual.
E Exclusive specifies that no other processes can access the physical file while the
program referring to the logical file has the file open.
S Shared specifies that other processes can both read and write to the physical file while
the program referring to the logical file has the file open.
P Protected specifies that another process can read but not write to the physical file
while the program referring to the logical file has the file open.
I Input specifies that processes can only read the physical file.
O Output specifies that processes can only write to the physical file.
IO Input/output specifies that processes can both read and write to the physical file.
