FW: Re: [SPSSX-L] Defining variables depending on values

Mike P-5
Hi Jurgen,

I got this through from Jon Peck, (guess he just forgot to press reply
all) SEE BELOW

So if you have the programmability installed you could use a couple of
lines of python

This functionality is built in to the spssaux2 module.  It's the
CreateBasisVariables function.  It discovers the values, generates the
variables, and creates descriptive labels.

Subject: Re: [SPSSX-L] Defining variables depending on values

Hi Jurgen,

I have a script that converts a categorical into a dichotomous, with a
bit of playing with the script you could make it output the categorical
value instead...

Just copy and paste into a script file and you can call it from spss,
under run script option

Public blnCreateSyntax As Boolean
Public arrValueLabels() As String
' holds the labels corresponding to the above values Public

new variables to be created Public arrVarLabels() As String Option

Subject: Defining variables depending on values

Dear listmembers,

I want to define a set of variables depending on the values of one other
variable.

Example:

VAR_X
2
2
3
3
4
4
5
5

The result should look like this:

VAR_X VAR_2  VAR_5  VAR_7  VAR_9
2   2
2   2
5   5
5   5
7   7
7   7
9          9
9          9

I'll already tried the vector-function in combination with a loop ... /
do if - structure, but the result is a variable set, that, for example,
contains 10 variables, whereof only four variables contain values.

Best regards

Juergen
