Appendix B File Definitions: Default Values
Appendix B summarizes the default file definition values that FCOPY uses
to open a tofile or fromfile. It contains two tables: table B-1 shows
default values for different types of fromfiles, and table B-2 shows
default values for different types of tofiles. The information stored in
the file label of an existing disk file always describes its
characteristics.
Items marked with a "plus" sign (+) are those most likely to cause
problems when you are copying from one device to another. Refer to the
File System Reference Manual (30000-90236) or Accessing Files Progammer's
Guide (32650-90017) for information about domains, buffers, and record
formats.
You can override a file's default definition before you issue an FCOPY
command. Simply redefine its characteristics using the MPE FILE command
and then use an asterisk (*) to backreference the FILE command in the
FCOPY command.

NOTE
1. $CTUL or $CTUR domain is ASCII (JIS for the HP 2645K
terminal) or binary, depending on the tofile.
2. A named disk file's access type is as follows:
For COMPARE: READ only.
For VERIFY: INPUT/OUTPUT.
APPEND when message files are used.
3. A named disk file has exclusive access for all functions
except COMPARE.
