How to use the -EMOD Y and the difference in results with and without the -EMOD.

Environment

Resolution

-EMOD Y
The -EMOD execution control statement marks the end of one module's control statements and data. Use -END to mark the end of the entire control stream. The -EMOD statement is optional.
The Y In column 7, CA Librarian suppresses all updating of the module if shifting during a -EDIT operation causes an overflow of data out of the range of columns being edited on any record.

The -EMOD Y is for -EDIT function and disallows update if operation causes shifting out of range.

For example, by changing "AAA" to "BBBBBBB", the data in the line would exceed 80 columns.
