You can create a UNIX file for access through BSAM or QSAM (DCB DSORG=PS), BPAM (DCB DSORG=PO), or VSAM, in any of the following locations:

• JCL DD statement
• SVC 99 (dynamic allocation)
• TSO/E ALLOCATE command
• UNIX System Services commands such as ISHELL, BPXCOPY, OPUT, OPUTX, and OCOPY

Before you begin: Be familiar with how to use JCL, TSO/E ALLOCATE, or SVC 99 to create a data set, and understand how to specify the FILEDATA and PATHMODE parameters. For more information, see the following material:
