[?]Fourgen:form:update:detail-lineitem-delete:4gl explanation please

Greetings Net.Wisdom, I am attempting to understand the 4gl that Fourgen generates in regard to line item deletes in the detail section of a header-detail screen when in the "update" option. Specifically I am looking at lld_delete() (detail.4gl) and the sql statement: delete from det_table where join_fld = m_rec.join_fld What vexes me is that when I run this statement in dbaccess (replacing m_rec.join_fld with an actual value) this deletes all the rows meeting this criteria; however, Fourgen 4gl manages to delete just the row that was F2'd (line-item deleted). Can someone please explain to me what I am failing to see and understand? How is it that Fourgen is able to use the same function for line-item deletes and record-deletes ("delete" from the ring menu)? Much thanks! -Todd Willamette Industries, Inc. -- Richard Shannon cpilot@teleport.COM Todd Bernhardt cpilot@teleport.COM
