Re: st: RE: condensing varlist non-categorical contents to a newvar

[Philipp Rehm <philipp.rehm@gmx.de>]

.
Your variable injurytype seems to be a string variable.
I haven't looked at how you want to recode it, but if it is a string 
variable, you will need to use quotation marks ("):

replace injurytype="minimal" if injurytype=="."
or
replace injurytype="minimal" if injurytype==""

It depends on how your missing values are coded.

HTH,
Philipp
