What's the difference between VAR A1 - A4 and VAR A1 - A4?
I guess you mean: difference between Var A1-A4 & Var A1--A4!
A1-A4: assumes the variable names as A1,A2,A3,A4 sequentially.
A1--A4 : writes all the variables of the data set which are between the variables: A1 & A4,
eg: it can be name,Id etc.
