I made a syntax called saveBackup.sps to do this job.
I include a syntax to define a save-with-date-macro and then I call that
macro with a number of variables.
I assume the file C:\temp\StandBackUp.sav exists. This can be any
existing file, in my case the file contains one variable called 's'
which has numeric value '1').
In the follwing example I make a backup of file C:\temp\xxx.sav to
directory C:\temp\backup\
INCLUDE 'c:\.....\SaveBackup.SPS'.
!Backup DirRoot= 'C:\' SubPath= 'temp' BackupPath= 'Backup' BasisNaam=
'xxx' .
The macro does the following:
- determines what date it is
- writes save-command syntax to a file (including date specification)
- opens file C:\temp\xxx.sav
- and saves it to
C:\temp\backup\xxxyear-month-day-hours-minutes-seconds.sav (e.g.
xxx20060718_14-55-33.sav)
Macro SaveBackup.SPS:
DEFINE !BackUp (DirRoot= !TOKENS(1) / SubPath= !TOKENS(1) / BackupPath=
!TOKENS(1) / BasisNaam= !TOKENS(1) / Naam = !TOKENS(1))
GET FILE='C:\temp\StandBackUp.sav'.
COMPUTE d = CONCAT('"',STRING(XDATE.YEAR($TIME),F4.0),
STRING(XDATE.MONTH($TIME),F2.0), STRING(XDATE.MDAY($TIME),F2.0),'_',
STRING(XDATE.HOUR($TIME),F2.0),'-', STRING(XDATE.MINUTE($TIME),F2.0),
'-',STRING(XDATE.SECOND($TIME),F2.0), '.sav"') .
LOOP IF INDEX(d," ")>0.
+COMPUTE SUBSTR(d,INDEX(d," "),1)="0".
END LOOP.
EXE.
COMPUTE a = "SAVE OUTFILE=" .
COMPUTE b = !QUOTE(!CONCAT('
"',!UNQUOTE(!dirRoot),'\',!UNQUOTE(!SubPath
),'\',!UNQUOTE(!BackupPath),'\',!UNQUOTE(!BasisNaam),'"+')) .
WRITE OUTFILE= 'C:\Temp\Save.SPS' / a .
WRITE OUTFILE= 'C:\Temp\Save.SPS' / b .
WRITE OUTFILE= 'C:\Temp\Save.SPS' / ' ', d .
WRITE OUTFILE= 'C:\Temp\Save.SPS' / ' /COMPRESSED.' .
EXE.
GET FILE= !QUOTE(!CONCAT(!UNQUOTE(!dirRoot),'\',!UNQUOTE(!SubPath
),'\',!UNQUOTE(!BasisNaam),'.sav')) .
INCLUDE 'C:\Temp\Save.sps' .
!ENDDEFINE .
Greetings, Max

This is another one that comes up from time to time. It's not entirely
simple, because it's dynamically modifying code - changing code based on
data. (In this case, the data is the current date.)
If you have SPSS 14, the best solution is probably with Python, which
I'm not up to speed on, yet, to post. For long before, the standard way
to generate dynamic code was to write the code to an external file,
often as a macro definition, and INCLUDE it. In your case, your
"(TODAY'S DATE)" should be a macro that evaluates to the date, in the
form you want it, IN QUOTES. (the pioneer and master of this technique
is Raynald Levesque. There should be a number of relevant examples on
his Web site, http://www.spsstools.net/.)
You'll have to modify this, but here's a solution I wrote and posted a
while back(*). It creates a macro !act that evaluates to
'c:\TempStor\SPSS\dd-MMM-yyyy hh-mm.sav'
It's tested code; this is SPSS draft output. There's some code that's in
just to trace what's happening, so it could be shortened.
