PN81268: THE ASMAOPT MACRO CHECKS THA VALUE OF THE SIZE PARAMETER INCORRECTLY IF IT IS CODED AS NNM. CODING AS NNNNK WORKS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The ASMAOPT macro checks the size parameter incorrectly
  if it is code as nnM.
  

Local fix

• Use nnnnK instead of nnM.

  * PROBLEM DESCRIPTION: The ASMAOPT macro checks the value of   *
  *                      the size parameter incorrectly if it is *
  *                      specified as nnM.  Specifying nnnnK     *
  *                      works.                                  *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The ASMAOPT macro incorrectly restricts the integer value for
  SIZE(intgM) option to less than 16 if the STORAGE parameter does
  not specify ABOVE.
  

Problem conclusion

• Macro ASMAOPT has been changed to remove the restriction for
  the SIZE(intgM) specification and the following documentation
  change has been made to clarify the behavior.
  
  Change in Manual SC26-3494-00 ('Installation and Customization
  Guide MVS & VM Edition'), Appendix A. High Level Assembler
  Options, page 159 and
  Manual SC26-8263-00 ('Installation and Customization Guide VSE
  Edition'), Appendix A. High Level Assembler Options, page 94,
  at the end of the notes associated with the SIZE option after
  the sentence:
  
     Use the STORAGE operand of the installation default macro,
     ASMAOPT, to specify the equivalent of the ABOVE suboption.
  
  add the following:
  
     If suboption intgK or intgM is specified without the MAX
     keyword, the STORAGE option is ignored and virtual storage
     is allocated by the operating system, either above or below,
     on a 'best-fit' basis.
  
  Change the following in the description of the STORAGE option:
  
  - Remove the following sentence from the description of the
    ABOVE keyword:
  
    ABOVE can only be specified if the SIZE option includes the
    MAX keyword.
  
  - Change 'Note:' as follows:
  
    Notes: 1. This option will only be honored if the SIZE option
              includes the MAX keyword.
  
           2. The STORAGE option can be specified as an assembler
              invocation parameter by specifying the
              SIZE(MAX,ABOVE),
              SIZE(MAX-integerK,ABOVE), or
              SIZE(MAX-integerM,ABOVE), option.
