Re: Position To in a display file pgm using embedded sql

["Peter Dow" <pcdow@xxxxxxxxx>]

Hi Phil,

Try FETCH RELATIVE PageSize FROM cursor INTO hostvariables, where PageSize
can be a negative number.  Assumming you're displaying a subfile with 10
rows on it, you'd have PageSize = -20.  If you're not using a subfile and
just want to go back one record, you could use FETCH RELATIVE -1 or FETCH
PRIOR.
