Use Table 1 to convert a JCL DD statement into dsname allocation text units. This table lists JCL DD statement parameters in alphabetical order, along with the equivalent verb code 01 text unit key and mnemonic. Some JCL DD statement parameters have multiple text unit keys associated with them. In these cases, the same JCL DD statement is repeated in the table for each text unit key associated with it.
JCL statement DD DCB subparameters are listed in Table 1, although you can code them directly on a DD statement without using the DCB parameter.
