+ - Move data window forwards

The + statement moves forwards in the work file (toward the end of the file). The position can be moved forwards by a given number of characters or to a record with a specified record mark.

Operation	Operands	F mode
+ [DUE]
+ [F3]
+	{n | ( [m [,...]] )}

If the statement is sent without operands by means of the [DUE] key or a function key other than [F3] then the position moves forwards by the number of records visible in the data window. Any column counters or lines hidden by messages, for example, are taken into account.

If the statement is sent without operands by means of [F3] then the position moves to the next record having any record mark (1..9). The statement +[F3] is therefore equivalent to +() [DUE] (see below).

n

Number of lines to be scrolled through forwards. Values between 0 and 99999999 are permitted for n. However, forwards scrolling stops when the last record in the work file is visible in the first screen line. The value of n determines the number of records by which the data window can be moved forwards independently of the currently set increment in the line number display or gaps in the record numbering.

m

Is one of the possible record marks (1..9) to which the position may be moved. It is possible to specify multiple record marks which must be separated by commas. The position moves forwards to the next record with one of the specified record marks - this is displayed in the first screen line of the data window. Marks with special functions (see section “Recordmarks” (Record marks )) are ignored here. If m is not specified then the position moves to the next record having any record mark (1..9).

Note

If the statement is sent with [F3] then it is important to make sure that only statement codes that can be sent with [F3] are specified simultaneously (see section “Statementcodes in F mode”). Otherwise, the operation is aborted during the analysis of the statement codes and the + statement is not executed.

Example

A column counter is displayed in the top data window which has been reduced with @SPLIT. The last line in the data window is hidden by the message EDT0901.

The + statement is to be used to scroll forwards.

The position scrolls forwards to the first line that was not previously visible (4.00).

For an example of moving to a record with a record mark, see the description of the @ON statement, format 4.
