Re: st: RE: truncate variable names

[SCHOUMAKER Bruno <bruno.schoumaker@uclouvain.be>]

Thanks a lot !

I agree it may seem a bad idea; Actually, I had a program running with 
variables names truncated to 8 characters (exported from SPSS using an 
old stat/transfer version) -  I received a new data set (same data, but 
with additional observations), exported from SPSS with a new version of 
stat/transfer, but with variables names longer than 8. And it would save 
me a lot of time if I could just re run the syntax with exactly the same 
variable names...

Best,

Bruno
