On a REG_NAMELIST request, you specify a starting and ending index value for registration block processing with the STARTINDEX and ENDINDEX keywords. Both keywords specify an index value into the set of registration blocks. The registration blocks in the storage area are numbered starting with 1.

• Use STARTINDEX to identify the first registration block in the storage area that the system is to process.
• Use ENDINDEX to identify the last registration block that the system is to process.
