replicating cases to a dataset in memory

I was trying to adapt a small demo on replicating cases with integer weights to a dataset in memory rather than a disk file. When I run the syntax below, I get

Warnings
Dataset stretch has no data.
Execution of this command stops.

I must be missing something obvious.

new file. data list list/x (f1) kount(f1). begin data 1 3 2 4 end data. dataset name short. execute. list. dataset declare stretch. dataset activate short. loop seq = 1 to kount. xsave outfile='c:\project\stretched.sav'. xsave outfile=stretch. end loop. execute. get file='c:\project\stretched.sav'. dataset name fromdisk. formats seq (f2). list. dataset activate stretch. formats seq (f2). list.

Re: replicating cases to a dataset in memory

Art, it looks like the command xsave cannot work with memory files - the line

xsave outfile=stretch.

is not working. You can use it only for data files (xsave out="C:/something".)

Best,

Jan

Hi Art. I can't find it in the Help just now, but I think the problem is that the OUTFILE for XSAVE cannot be a dataset--it has to be a .SAV file written to disk. One puzzling thing is that you get no error or warning for your line "xsave outfile=stretch."

Question for SPSS: If XSAVE cannot write to a dataset, why is there no warning here?

Cheers,
Bruce
