first section creates vg_sales_basic as the dataset however line below it uses vg_sales_cook dataset

[ravi_k]

 it wont run in order the way it is I dont think, since the first section creates vg_sales_basic as the dataset however the line below it uses vg_sales_cookd as the dataset.

Can some one please explain it 

libname ssr 'E:\Users\ssr180000\Downloads';

data vg_sales_basic;
set ssr.videogamesales_main;
run;

proc glm data = vg_sales_cookd;
class Rating(ref='E10+') Platform(ref='PC') Genre(ref='Strategy');
model log_global_sales = Rating Platform Genre Weighted_Score Critic_Score User_Score User_Count Critic_Count Generation Generation*Platform / solution;
where cookd < 4/4155;
output out=vg_sales_safe;
run;
quit;

What do you need explained?

[ravi_k]

the code at the start in line 2 creates 'vg_sales_basic' as the dataset but in line 6 'vg_sales_cookd' is used as a dataset. I want this to be explained

Assuming there is not a work.vg_sales_cookd, dataset then you are correct the PROC GLM will error

It has nothing to do with the data step that creates work.vg_sales_basic.
