Embedded SQL/C scrollable cursors

The scrollable cursor feature is now available with the ESQL/C pre-processor. Similar to Client-Library implementation of scrollable cursors, ESQL/C application programmers can now set the current position anywhere in the result set by specifying a NEXT, PRIOR, FIRST, LAST, ABSOLUTE or RELATIVE clause in an OFFSET statement. It implements a scrollable cursor that is read-only with either an INSENSITIVE or a SEMI_SENSITIVE property.
