When you issue a REQUEST=DELETE_NAMELIST request, you must specify a buffer that contains the list of name elements. You can use a single buffer (the BUFFER keyword) or multiple buffers (the BUFLIST keyword). Either method enables you to build a maximum of 2048 name elements.

For information about whether to use a single buffer or multiple buffers and for information on selecting buffer attributes, see Design Considerations for Choosing the Buffer Format.

Use the STARTINDEX and ENDINDEX keywords as index values to identify the name blocks in the buffer area to be processed. The name blocks are numbered starting with 1. The name blocks are processed sequentially beginning with STARTINDEX and continuing through ENDINDEX.
