Fixed Block ASA: All blocks and all logical record are fixed in size. One or more logical records reside in each block and the use of ASA characters on z/OS.
Fixed Block MACHINE: All blocks and all logical record are fixed in size. One or more logical records reside in each block and the use of MACHINE characters on z/OS.
Fixed MACHINE: Each string contains exactly the number of characters defined by the string length parameter and the use of MACHINE characters on z/OS.
Variable: The length of each string is less than or equal to this number.
Variable ASA: The length of each string is less than or equal to this number and the use of ASA characters on z/OS.
Variable Block: Blocks, as well as logical record length, can be any size. One or more logical records reside in each block.
Variable Block ASA: Blocks, as well as logical record length, can be any size. One or more logical records reside in each block and the use of ASA characters on z/OS.
Variable Block MACHINE: Blocks, as well as logical record length, can be any size. One or more logical records reside in each block and the use of MACHINE characters on z/OS.
