Sequence numbers

The sequence number area can be used to label a source statement line. The content of this area can consist of any character in the character set of the computer.
The sequence number area of a PL/I file spans the eight columns to the right of the right margin. Enabling the Sequence Number preference, text can be kept in the identification area when you edit a file. Additionally, there are several other options you can select related to managing text in the sequence number and identification areas of your file.
Smart copy
Text in the sequence number and identification areas is replaced by spaces when you copy the text. If Insert sequence numbers into new lines option is enabled, lines that are pasted into the file are renumbered.
Smart Join Lines
Text in the sequence number and identification area and trailing white spaces are deleted when lines are joined.
Insert sequence numbers into new lines
Sequence numbers are inserted when adding new lines to a file. The location of the sequence numbers is determined by the Start numbering at column 1 option.
Resequence numbers when necessary
Sequence numbers are renumbered when there is not enough available numbers at the location where new lines are being pasted. This feature requires the Insert sequence numbers into new lines preference to be enabled.
