110906 LBC: Logical Block Copy For RSX Version: 89.237
Submitted by: Thomas R. Wyant III, E.I. duPont de Nemours & Co.,
Operating System: RSX-11M-PLUS V3.0 Source Language: FORTRAN 77,
MACRO-11 Memory Required: 32KW Keywords: Utilities - RSX-11
Abstract: LBC provides a non-structured disk copy facility for
direct-access media under RSX. All or part of a disk
(mounted foreign) or a file may be copied to another disk or
file, or to another location on the same disk or file. In
the case of file-to-file operations, the attributes of the
input file can be preserved. Because up to 64 blocks are
moved at a time, performance is reasonable. Error recovery
is done by reducing the number of blocks per QIO and
retrying the operation; if a single-block QIO fails, the
error is logged and a block is skipped on both input and
LBC can be invoked in any of the standard ways for an RSX
utility. The command interface is DCL-like, and includes
prompts for missing information.
Full default file name support as documented requires the
PRMS$ directive (ie - RSX-11M-PLUS V3.0 or greater). Older
RSX-11M-PLUS systems or RSX-11M systems, require more typing
but should work otherwise.
Notes: Executable and/or object code is included.
Changes and Improvements: Corrected calculation for high block number
Restrictions: Operating System RSX-11M-PLUS V3.0 or later is required.
