Dear Statalisters,

For the longest time I have been trying to find ways around certain 
commands that would involve string variables, but I can't believe that 
these commands really don't exist. Hence my question: For example, 
if "grain" is a string variable, how do I do an operation such as "drop 
if grain==wheat"? Similarly, how do I create value labels for string 
variables. For example, if I want the variable "grain" to have the 
value label "crop" when it takes on the value "wheat" and "barley"? I 
would be delighted if I didn't have to find laborious ways of data 
manipulation where dealing directly with the string variables would be 
much easier.

Thanks,
Tewodaj
