Enhanced Allocation Management functions

To set allocation attributes to specific values, use Enhanced Allocation Management function keywords.

Note:

The underlined portion of the keyword indicates the minimally acceptable abbreviation.
$NULL indicates that a particular attribute value should be set such that it appears that it was not specified by the user.
The default that is listed is the default for the Advanced Allocation Management keyword, it is not the default that is assigned to the attribute by the operating system (unless otherwise specifically noted).
Where applicable, the JCL, IDCAMS, data, management, and storage class equivalents are provided. For the data, management, or storage class equivalents, the field name from the appropriate ISMF panel that is used to define the class is listed.
The use of numeric suffixes is permitted.
When you use the Enhanced Allocation Management functions, it is your responsibility to ensure that the values are consistent and valid to the operating system.
