JCL DD statement DCB subparameters and equivalent text units

Use the following table to convert JCL DD statement DCB parameters into text units. The table lists JCL DD statement DCB subparameters in alphabetical order, along with the equivalent verb code 01 text unit key and mnemonic. Some DCB subparameters have multiple text unit keys associated with them. In these cases, the same DCB subparameter is repeated in the table for each text unit key associated with it.

The following JCL statement DD DCB subparameters do not have equivalent text units and do not appear in the table:
The following text unit keys are obsolete. The system checks these text units for syntax and ignores them. They appear in Table 1 and are described in the text unit descriptions for your reference when using old code, but they are not included in this table.
