string length limitation

[Mumdzhiev]

Hi all,

My question is about going beyond the spss string length limitation to 32 k
i worked nicely within, but unfortunately couldn’t go over the 32 kb limit size for strings in spss, fe for really long var lists as a macro and other stuff; its not only referring to loops fe for frequencies (1000 var maximum), so please consider this more generally,
Is it likely to cover this easy in python, and can you recommend some further strategies for handling such a limit?
Do they apply to the server version also?
Ill be thankful for any comments/replies.

Please provide more detail on what you are trying to do.  The 32K limit applies specifically to the maximum width of a string variable.  I have seen some really long commands, but I doubt that I have ever seen one command that was more than 32K.  I don't know of any limit on the length of a command, although there is a line length limit of 251 beyond which wrapping is required.

You should be very happy that strings are supported to that length.
The limit used to be 255 characters.
Have you thought perhaps to use 2 strings?
I can't imagine what you are trying to do in my wildest imagination.
Many here can attest to the extent to which my imagination runs wild.
Be describe and be specific what you are attempting to do.
The manner in which you are trying to do it is likely ridiculous.

Thanks Jon, David,

we were testing the SPSSINC SELECT VARIABLES extension on recent spss versions, while exporting many many varlists, and this is really a very fine way to capture them all in a macro, but on long varlists (more than 10000 items) got always the error massage for the string length limit;
the question was to improve the classical oms export to sav, with some given constraints as fe not being able to flip aso because of memory issues, not all spss modules are available, given different spss versions, and how to  organize the whole thing; there may be lot of options as split datasets or varlists in product categories and sort of, handling the error massage on the extension tool was another; i was wondering if the string list from the SELECT VARIABLES macro could make it

Hi Jon,

thanks for replying.
Heres the syntax for the extension run which runs on shorter lists.

SPSSINC SELECT VARIABLES MACRONAME="!allvars"
/PROPERTIES LEVEL=NOMINAL
ROLE=ANY
/OPTIONS ORDER=FILE PRINT=YES IFNONE=ERROR SEPARATOR=" ".

the note:

Variables Listed in Macro !allvars
***A string goes here that exceeds 32,767 bytes***

then, the macro !allvars istn available.

It would be great if you solve this!!!

I am still not quite clear on when the error appears.  Do you get an error when the SELECT VARIABLES code is run, i.,e., when the macro is defined, or do you get it when you attempt to use the macro.
