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