Parameter in IEASYSxx (or specified by the operator)

FIX=   {aa                      }
       {(aa[,L][,NOPROT])       }
       {(aa,bb,...[,L][,NOPROT])}

The two characters (A-Z, 0-9, @, #, or $) represented by aa (or bb, etc.), are appended to IEAFIX to form the name of one or more IEAFIXxx members of SYS1.PARMLIB. The system defaults to no FLPA, if you fail to specify the option in one of the following ways:

FIX keyword included in the IEASYSxx member.
FIX keyword entered by the operator at IPL.

The LPA modules that are fixed in storage are also page protected, by default. If an attempt is made to store into a page-protected module, a protection exception occurs. However, an installation can use the NOPROT option to override the page protection default. When NOPROT is specified, the LPA modules in the IEAFIXxx parmlib member(s) are not page protected in storage.

If the L option is specified, the system displays the contents of the IEAFIXxx parmlib member(s) at the operator's console as the system processes the member(s).
