- Douglas Boling
- 1989 No. 1 (Utilities)
-
-
- Purpose: A memory-resident utility that copies files in the background so
- the user does not have to wait until the copying is completed before continuing
- his work.
-
- Format: [d:][path]BCOPY [source [target]] [/X][/U]
-
- Remarks: The source and target parameters have the same usage in BCOPY as
- in the DOS COPY command, save that if the source is a directory, BCOPY will not
- automatically assume an implicit \*.*. DOS wildcard characters (* and ?) are
- supported, however, and a source filename need not be repeated as part of the
- target filespec unless the name is to be changed. If initially run with the /X
- command line switch, BCOPY will use one page of Expanded memory for its data
- buffer, thus saving 4 KB of conventional RAM. Run with the /U switch, BCOPY
- will uninstall itself from memory, if possible. BCOPY will always complete all
- copying tasks in its queue before deinstallation.
-
- BCOPY does not support the DOS COPY /A and /B switches: it makes
- straight binary file copies and does not stop at a Ctrl-Z end-of-file marker.
- Nor does BCOPY allow using the plus (+) sign to combine multiple source files
- into a single copy. Note: unlike the DOS COPY command, BCOPY does not return a
- Target Disk Full error message, so care must be exercised to ensure that
- adequate storage space is available. Since the principal use of BCOPY is to
- load files to a RAMdisk during the execution of an AUTOEXEC or other batch file,
- however, this should not present a problem in normal use.
-
- Available for downloading from PC MagNet (see the BCOPY by Modem
- sidebar), BCOPY.COM is already compiled and ready to run. BCOPY.BAS will
- automatically create BCOPY.COM when run once in BASIC. To create BCOPY.COM from
- the BCOPY.ASM source code requires use of a macro assembler (IBM or Microsoft,
- Version 2 or later) and the following commands:
-
- MASM BCOPY;
- LINK BCOPY;
- EXE2BIN BCOPY BCOPY.COM;
-
- ** Special Note: This utility is also a mentioned in the Ziff-Davis Press
- book "PC Magazine's DOS 5 Techniques and Utilities" by Jeff Prosise. Both
- this DOCumentation file and in the book's utility reference stand as correct.
