As a stop gap measure, we are using Google's custom search engine service.

Although a CALLP will work, you should really be using EVAL since the
system function returns a value the 10I on the Pr line above.  This is set
non-zero in the event of an error.  The actual message that caused the
error will be found  in the variable _EXCP_MSGID which has to be imported
like so:

      D ErrorCode       S              7    Import('_EXCP_MSGID')
