The BSFSYS structure is a structure to specify the input file system.
The size of the area when the area of BSFSYS structure is secured can be calculated by using BS_INPFSYSSIZE(n). BS_INPFSYSSIZE(n) is a macro to calculate the size of BSFSYS structure with n pieces of input files system information.
typedef struct {
unsigned long entry_no;
unsigned char filesys[1];
} BSFSYS;BSFSYS structure member
In the following, it explains about the member of the BSFSYS structure.
entry_no
This specifies the number of input file systems.
filesys[n]
This specifies the file system of input files.
A specification of input file system sets 1 input file as a file system of a file specified for file_addr[i] of BSFILE structure should be set in filesys[i]. When the number of input file systems is less than the number of input file path names, the file system specified at the end is applied to the file that remains. The file system that can be specified is shown below.
Define value | File system |
|---|---|
BSFS_DOSFS | Native file system of the system (Default) |
BSFS_COBS | NetCOBOL file system (sequential file) |
BSFS_COBS64 | NetCOBOL file system (BSAM-compatible sequential file) |
BSFS_COBR | NetCOBOL file system (relative file) |
BSFS_COBI | NetCOBOL file system (indexed file) |
BSFS_MFCS | Micro Focus COBOL file system (sequential file) |
BSFS_MFCR | Micro Focus COBOL file system (relative file) |
BSFS_MFCI | Micro Focus COBOL file system (indexed file) |
BSFS_BTRV | Btrieve file system |
Note
PowerBSORT cannot access files opened by the NetCOBOL file system in exclusive mode. In addition, if the NetCOBOL file system (indexed file) is specified, PowerBSORT cannot access files opened by the NetCOBOL file system in shared mode. For more details on shared mode and exclusive mode, refer to the documentation of your NetCOBOL file system.
Even if the NetCOBOL file system (BSAM-compatible sequential file) is specified, if your NetCOBOL file system is not compatible, files are handled as NetCOBOL file system (sequential file). For details on BSAM compatibility, refer to the documentation of your NetCOBOL file system.
If the NetCOBOL file system (BSAM-compatible sequential file) is specified, record exclusivity may not be maintained, depending on the NetCOBOL file system.
Micro Focus COBOL file system (indexed file) can be specified only for the file system of the input file.
A Micro Focus COBOL indexed file in which data is compressed cannot be specified for the input file.
