If the statement code + is sent with the function key [F1] then the position is set to the next record that has the same structure depth as the specified record.
The structure depth is the distance of the first non-blank character from the start of the record. It makes no difference whether the record is displayed as of column 1 or whether the screen section has been shifted to the right.
If a structure symbol other than a blank has been defined (see @PAR STRUCTURE) then only records which contain this character are considered. If the blank is defined as the structure symbol then all the records are considered. The default value for the structure symbol is @.
Statement code | Key |
+ | [F1] |
If no record with the same structure depth is found then the position remains unchanged.
If the specified record does not contain a structure symbol then the statement code is rejected with the message EDT5354.
Example
This example assumes that the blank has been defined as the structure symbol using @PAR STRUCTURE=' '.
The statement code + is entered in line 4.00 and is sent with [F1].
The position has been moved to the next record with the same structure depth.
