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

What is the length assigned to the target variable by the scan function?
