Insertion after implicit deletion

The work file in which the lines are to be inserted is implicitly completely deleted prior to insertion, i.e. the current increment and the current line number are both 1.0000 immediately before insertion. Lines are then inserted starting at the current line number(=
1.0000).

The line numbers of the other lines that are to be inserted are determined by adding the current increment (= 1.0000) to the line number of each last inserted line. On completion of the insertion operation, the new current line number is determined from the line number of the last newly inserted line plus the current increment.

The following table indicates the EDT statements for which this procedure is used (in the case of some EDT statements, other procedures may be used in the event of a different format or different operands).

Statement	Comments on operands	General comments
@ON Format 4 + 5	Without specification of the KEEP and OLD operands
@OPEN Format 2	Open a copy of SAM files without specifying the KEY operand in a work file in which a file has already been opened with @OPEN (format 2).	Before the second @OPEN statement, a @CLOSE statement is issued, i.e. the work file is implicitly deleted.
@SHIH		The output is sent to work file 9.
@STATUS	Without target specification on output in F mode	The output is sent to work file 9.
