Example	equ vm to char(253) names = "john":vm:"paul":vm:"george":vm:"ringo" names = delete(beatles,1,3) This example deletes the value "george" from the dynamic array "names". The reference to attribute 1 is required. The absence of attribute marks in "beatles" requires it be treated as a single attribute. read cust.item from cust.file,item.id else cust.item = "" locate(date(),cust.item,date.flds;vx) then write delete(cust.item,date.flds,vx) on cust.file,item.id end
Warnings	Attempting to delete attribute 0 is undefined and should be avoided. In R83, the delete function does not work on dimensioned arrays.
