Re: st: Dropping Subset of Variables

["Gauri Khanna" <gwkhanna@hotmail.com>]

Dear Neil,

Thanks for your prompt reply.

Unfortunately, the wild card does not help because I have other variables in 
my data set that have _02, _03 etc. attached and which I may want to keep.  
I want to try and get rid of these listed variabls only with the _02 to _46 
suffix.


Is there any way around this barring doing it individually for each 
variable?

I looked through the manual and users guide but did not get any inspiration.

Regards,

Gauri
