Problem:

Micro Focus documentation describes WRITELINE for the extfh.cfg configuration file as:

WRITELINE -  Determines whether mainframe or PC behavior is used for WRITE record.

What does this actually do and what type of file does it affect?

Resolution:

The WRITELINE option only affects line-sequential files that contain qualified writes. When switched on any unqualified writes are treated as a write after 1 making it a qualified write.

Note: Set WRITELINE=OFF if  PC print behavior for WRITELINE is desired  when using mainframe dialects.
