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 COBOL file is columns 1-6. The identification
area spans eight columns starting at Margin R. When you enable the Sequence
Number preference, text can be kept in the identification
area when you edit a file. You can also choose options that determine
how the COBOL Editor manages text in the sequence number and identification
areas of your file.
For more information about setting options for sequence number
handling, see Enabling sequence number handling
