range with hyphen and colon

[anming]

hyphen and colon can effectively express a range, such as

input name $1-6   /*6 positions for a name

array score (4) score1-score4;

var1=sum(of col2-col11, of col13-col30);

sheet="name-class $A2:C6"   /*a data range of the excel sheet of class

'A' - 'F'; letters range from A to F

'A-F' a string of three characters.

Any other cases?

There's the double-hyphen which can be used for variable lists to denote you want consecutive variables from a data set.

proc print data=sashelp.class;
    var age--weight;
run;

 and a variation if you only want numeric variables in the variable list

proc print data=sashelp.baseball(obs=20);
    var name team crbb-numeric-salary;
run;

and a similar (and obvious) modification gets you all of the character variables in the list of variables.
