{
{   This request scans for delimited SCL string expressions within a  line  of
{ text.   Each  expression  is evaluated and the result replaces the delimited
{ text including the delimiters.
{
{   If a second delimiter is not found in a line, the end-of-line  is  treated
{ as  the  second  delimiter.   Two consecutive delimiters are replaced with a
{ single delimiter.
{
{   If an expression cannot be  evaluated  the  original  text  including  the
{ delimiters  is  not  replaced.   If the new line of text exceeds the maximum
{ line size, the original line  is  returned.   In  both  cases,  the  request
{ terminates with an appropriate status.
