{
{   The CLP$WILD_CARD_FILE_EXPANSION request expands a file reference
{ containing "wild card" characters and/or the special path element $ALL into
{ an SCL "list of file" value.  Pointers to both the first (head) and last
{ (tail) elements of the result list are returned to facilitate joining the
{ result list with other lists.

{
{ EVALUATED_FILE_REFERENCE: (input)  This parameter specifies the file
{       reference to be expanded.
{
{ EXPANSION_OPTION: (input)  This parameter specifies whether only files, only
{       catalogs, or both files and catalogs, are to be included in the
{       resulting list of file.
{
{ WORK_AREA: (input, output)  This parameter specifies an area of storage that
{       will be used to construct the result list.  The current position of
{       this sequence pointer is updated to reflect the amount of storage used
{       by the request.  The result list is completely contained within the
{       used part of this sequence.
{
{ RESULT_LIST_HEAD: (output)  This parameter specifies the first node of the
{       resulting list of file.
{
{ RESULT_LIST_TAIL: (output)  This parameter specifies the last node of the
{       resulting list of file.
{
{ STATUS: (output) This parameter specifies the request completion status.
