SUMMARY
=======
The text below demonstrates using NMAKE and the ALL target-dependency (an NMAKE
keyword) to copy or backup files that are out-of-date with respect to the
previous copy or archive.
MORE INFORMATION
================
The steps below create a .MAK file that copies the AUTOEXEC.BAT and CONFIG.SYS
files to a directory named C:\BACKUP:
1. Use a text editor to create COPY.MAK that contains the following text:
ALL: c:\backup\autoexec.bat c:\backup\config.sys
c:\backup\autoexec.bat: c:\autoexec.bat
copy c:\autoexec.bat c:\backup\autoexec.bat
c:\backup\config.sys: c:\config.sys
copy c:\config.sys c:\backup\config.sys
NOTE: The .MAK file above copies the AUTOEXEC.BAT files from the source
directory (C:\) to the target directory (C:\BACKUP). The files are copied
only if the files in the source directory have an older time/date stamp than
the files in the target directory.
2. Create the C:\BACKUP directory if it does not already exist. To do so, type
the following at the MS-DOS command prompt:
" mkdir c:\backup" (without the quotation marks)
3. To backup any changes you made to your AUTOEXEC.BAT or CONFIG.SYS files, type
the following at the MS-DOS command prompt:
" nmake /f copy.mak" (without the quotation marks)
NMAKE processes only one dependency per makefile. If the makefile did not include
the ALL target-dependency (an NMAKE keyword), only the first file would be
copied and the second copy command would be ignored completely. The ALL target
creates a dependency that depends on the completion of every task in the
makefile. Without this statement, two dependencies are declared, only one of
which would be processed.
Page 645 of the "Microsoft Basic 7.0: Programmer's Guide" for versions 7.0 and
7.1 presents a similar example. However, this example lacks the ALL
target-dependency and does not work correctly as presented.
