Villas,
var a1-a4 ;
if used in a proc will act upon only sas variable a1 a2 a3 and  a4

but var a1--a4;
could have another meaning depending of the sas table upon it is working
if you have a table constructed with this sequence of variable
.....z   a1 b1 c1 a2 b2 c3 a3 b3b c3 a4 b4 c4  n2...
         ------------------------------------
the proc will act upon  a1 b1 c1 until c3 and a4

HTH
