SPSS 15 LOOP-XSAVE warning message
 
|
Using XSAVE in a LOOP in SPSS 15, I got a new warning message:
>Warning # 142. Command name: XSAVE >LOOP has no effect on this command. What is it intended to mean? XSAVE is, has always been, a transformation command. In a LOOP, it's executed once per loop pass, though execution may be suppressed by DO IF within the LOOP. It seems to work the way it always has; see SPSS 15 draft output, below.

Take out the LOOP and you'll get identical results. Loop doesn't control the XSAVE.

I must confess that I am also mystified by this warning. There is an example in the data management book that uses XSave with Loop to "expand" single cases into multiple cases. AFAIK, prior to SPSS 15, it didn't produce this warning, but now it does. It still works, but you get this warning in the middle of the XSave command.
DATA LIST FREE /Age Female Male. BEGIN DATA 20 2 2 21 0 0 22 1 4 23 3 0 24 0 1 END DATA. LOOP #cnt=1 to SUM(Female, Male). - COMPUTE Gender = (#cnt > Female). - XSAVE OUTFILE="c:\temp\tempdata.sav" /KEEP Age Gender. END LOOP.

This is a known 'bug' in SPSS 15. Just ignore the warning.
