Error message: variable is uninitialized

[AnneW]

Hi Everyone,

I'm new to SAS and I'm having trouble fixing this error message: variable color is uninitialized. Some of the suggestions I have found elsewhere on how to fix this don't seem to apply (the original variable is in the dataset and I haven't misspelled anything). Any other ideas on how to fix this? Also, I'm trying to convert a character variable to a new numeric variable in this code.

Example:

data newdataset;

color2=.;

if color="black" then color2=1;

if color="red" then color2=2;

run;

You probably need to add a SET statement to bring in your original dataset that has the variable COLOR.
