- Copying times are affected by many factors, including CPU speed, disk
- drive hardware, disk and directory fragmentation, and whether
- datestamping (requiring a physical track select to the !!!TIME&.DAT
- file) is being done. A set of copy speed tests was performed to compare
- the performance of ACOPY22, ACOPY30, AC49 and COPY164 in one specific
- and consistent environment on an 4mhz AMPRO system running NZCOM/ZSDOS.
- The copy utility under test was run from MDISK_ramdiskA using a copy
- alias, timed with TIME.COM, to copy 18 files/204k from floppy_diskC
- (96tpi with 3ms step rate) to floppy_diskD (48tpi with 6ms step rate)
- without CRC verification. The difference in the starting and ending
- TIME.COM readouts gave the elapsed times. Source and destination
- directories were prelogged. The ZR/ZSDOS copy utilities AC49 and
- COPY164 were run as comparisons.
-
- Percentages shown are improvements in copy time required by
- ACOPY30 over the time required by ACOPY22 under the same
- conditions: (1-(acopy30_time)/(acopy22_time))*100%. It should
- be noted that these times and percentages could vary greatly
- under different conditions and serve mainly to show the general
- degree of improvement that can result from source and destination
- disk directory caching.

- ; Revision History
- ; ----------------
- ;
- ; 02/16/90 Now caches up to 256 source and 256 destination disk
- ; v3.0 directory entries in RAM, based on Hal Bower's SPEEDUP
- ; RSX, for extra fast copying, especially when using
- ; floppy disks. Fixed bug in disk free space routine and
- ; adapted it and DOS checking routines that should enable
- ; ACOPY30 to run properly under CP/M 3.0. Added two new
- ; options: 'A' (inactivated in distribution release but
- ; may be user-activated by patching) to limit copying to
- ; directory and not system files, and 'Y' to allow making
- ; destination files system files.
- ; - Terry Hazen
- ;
- ; 06/07/89 Unreleased version fixing long-time bug in DELARG that
- ; v2.2a doesn't properly delete last argument. Doesn't really
- ; affect operation but helps tidy up loose ends.
- ; - Terry Hazen
- ;
- ; 06/03/89 Fixes bug in ZSDOS datestamping functions by zeroing
- ; v2.2 FCBs and setting user numbers before making the ZSDOS
- ; datestamping calls. Otherwise identical to ACOPY21.
- ; - Terry Hazen.
- ;
- ; 05/16/89 Added optional third filename specification for files
- ; v2.1 to be excluded from copying. Will copy a file only if
- ; sufficient free space exists for it on the destination
- ; disk. Added 'D' option to archive the destination
- ; files. For mnemonic consistency, the 'A' option has
- ; been renamed to 'S' and the 'S' option has been renamed
- ; to 'X'. Reorganized the command line help screen option
- ; sequence by function and added default "Don't" prefix
- ; for ON when no other ON message exists. Added support
- ; for the DRVEC valid drive vector in the extended ZCPR3
- ; environment. Now automatically copies datestamps from
- ; source to destination files when operating under either
- ; Z80DOS or ZDDOS/ZSDOS. New 'C' option allows suppression
- ; of datestamp copying. Sets the ZCPR3 program error flag,
- ; if present, depending on the type of error.
- ; - Terry Hazen
- ;
- ; 11/17/88 Added separate 'A' option for archiving source files.
- ; v2.0 'N' option still copies only non-archived files, but
- ; no longer automatically archives source files. Using
- ; both the 'A' and 'N' options is the same as using the
- ; old 'N' option. ACOPY20.PAT is now the correct file.
- ; - Terry Hazen
- ;
- ; 10/27/88 Added user patch area for things like Z80DOS patches.
- ; v1.9 Included in the user patch area, but not activated,
- ; are Gene Nolan's routines from ACOPOZ8D.Z80 for
- ; implementing date stamping under Z80DOS. See ACOPY.PAT
- ; for more information. Also added 'V' option to allow
- ; turning verification on or off.
- ; - Terry Hazen
- ;
- ; 05/06/88 Revised to support user numbers up to 32 and to operate
- ; v1.8 correctly with the ZCPR3 GO command. Now always resets
- ; destination filename archive bit.
- ; - Terry Hazen
- ;
- ; 12/11/87 Shortened status message display to remove intermediate
- ; v1.7 status messages from final display line.
- ; - Terry Hazen
- ;
- ; 10/30/87 Added du: to filename displayed on error return.
- ; v1.6 Files not matching the attribute specification are
- ; no longer displayed. Eliminated the '*' AND option.
- ; Changed the 'A' option letter to 'N' to better specify
- ; NON-archived files. Revised the help screen.
- ; - Terry Hazen
- ;
- ; 09/03/87 Limited release. Revised option display and status
- ; v1.5 messages and added '- Source Archived' status message.
- ; Changed QDELET to allow different lengths of strings
- ; to be deleted. Fixed typo in ZINIT routine that always
- ; reflected ZCPR3 QUIET flag setting regardless of what
- ; our flag's initial setting was.
- ; - Terry Hazen
- ;
- ; 03/10/87 Version 1.4 release. Added full ZCPR3 compatibility.
- ; v1.4 When operating in a ZCPR3 environment, accepts dir: as
- ; well as du: form, gets screen width, quiet flag,
- ; maxdrive, and maxuser from ZCPR3 environment, sets
- ; ZCPR3 program error flag if errors occur, sets ZEX
- ; status flag to 2 to suppress automatic input. Program
- ; name in HELP message is derived from external FCB.
- ; ZCPR3 features are ignored if ZCPR3 environment is not
- ; present. Displays the number of files copied on
- ; completion of the program. Program name, maxdrive,
- ; maxuser, screen width may be modified by patching for
- ; non-ZCPR3 applications. A patch location also allows
- ; cancellation of the 'Files Copied' display.
- ; - Terry Hazen
- ;
- ; 02/17/87 Internal, unreleased version. Added M (Move) option
- ; v1.3 to delete the source file after the copy is complete.
- ; Revised source to Z80 code for smaller size and faster
- ; assembly using Z80ASM.
- ; - Terry Hazen
- ;
- ; 09/15/86 Version 1.2 release. Added S (Skip) option to skip
- ; v1.2 copying if destination files of the same name already
- ; exist.
- ; - Terry Hazen
- ;
- ; 07/25/86 Version 1.1 release. Improved command line help
- ; v1.1 request parsing so that initial filename character
- ; can be '/' or '?' without calling up the help screen.
- ; Changed attribute option entry to allow default ORing
- ; of attribute selections. Added '*' option to change
- ; the attribute logic to AND (as in version 1.0).
- ; - Terry Hazen
- ;
- ; 06/03/86 Initial release.
- ; v1.0 - Terry Hazen
