Weird behavior "data list" command in Python block

[Ruben Geert van den Berg]

Dear all,

The following code is correct but is not mprinted back properly.

set mpr on.

begin program.

dir='d:/t1/'

import spss

for filno in [str(i) for i in range(3)]:

    spss.Submit("""

data list free/id.

begin data

%(filno)s

end data."""%locals())

end program.

yields

 854  0 M>  data list free/id. 

 855  0 M>  begin data 

 856  0 M>  end data. 

 

>Warning # 9.  Command name: end data 

>An END DATA command appears where it is not required.  It will be ignored.

First: where did "filno" (line 8) go? Second: why do I get this warning? "end data." is needed all right here.

When I add a bit more code, the result gets even weirder.

begin program.

dir='d:/t1/'

import spss

for filno in [str(i) for i in range(3)]:

    spss.Submit("""

data list free/id.

begin data

%(filno)s

end data.

sav out "%(dir)sfile_%(filno)s.sav"."""%locals())

end program.

yields

 878  0 M>  data list free/id. 

 879  0 M>  begin data 

 880  0 M>  sav out "d:/t1/file_0.sav". 

 881  0 M>  BEGIN PROGRAM '# 

'.

This code runs fine and gives no more warnings but nevertheless two lines that should be mprinted aren't. Is this a bug? Could anybody explain what's going on here?

TIA!

There are some tricky things that happen when processing multi-line Submit calls, especially with the call containing a mode switch to text that is not actually a command.  Your code is actually working.  If you change data list free to data list list, you don't get the error message.
