∗The following values are possible for file type:
U = Enscribe unstructured R = Relative
E= Entry-sequenced K = Key-sequenced
∗∗This is the standard Guardian file attribute that stands for the maximum record length.
∗∗∗This value represents the Compaq responder default for NBS-9 files on an open. If you open an NBS-9 file without specifying the file attributes to return for the files in the directory, the Compaq responder defaults the parameter setting to the filename attribute only. If you do specify file attributes, the Compaq responder returns the specified file attributes for the files in the directory.
∗∗∗∗Line numbers are not preserved. If the value specified for the max-extents attribute is exceeded, max-extents is automatically increased (in increments, up to the system limit) and the lines renumbered.
The maximum number of lines allowed for file type 101 is 10,000,000. For more information, see the Guardian Procedure Calls Reference Manual.
Note. If a DEFINE by the name of _ZOSF_FIXED_AS_UNSTRUCT exists when the FTAM processes are started, and the string-significance parameter is set to FIXED in the request, the file created or selected will be an unstructured file with maximum-string-length of 4096 bytes.
