How can I merge LISS data in the Panel Data Archive/Questasy?

Any variable from any LISS study that is published in the LISS Panel Data Archive can be merged (in STATA or SPSS) by using nomem_encr as the key variable. Another way to do this is to create a variable basket (see manual), which generates a file where the variables in the basket are merged on the basis of nomem_encr.
