SAS: Double dash

Use double-dash to indicate a range of variables (in the order they are defined in the program data vector, I assume).

Source code:

    data _null_;
    input a b c $ d e $ f;
    put b--e;
    datalines;
    1 2 w 4 x  6
    2 4 y 8 z 12
    ;
    run;


Log:

    2 w 4 x
    4 y 8 z

SAS: Concatenate strings and numbers using CATX function

No more trim'ing and left'ing!  SAS' CATX function lets you concatenate strings and numbers!

Source code:

    data _null_;
    attrib result length=$20;
    input name $ date_as_number : anydtdte12. ;
    date_as_string = put(date_as_number, mmddyy10.);
    result = catx("*", name, date_as_number);
    put result=;
    result = catx("*", name, date_as_string);
    put result=;
    datalines;
    Cora 19840723
    Hannah 19880626
    Emma 19900411
    ;
    run;

Log:


    1    data _null_;

    3    input name $ date_as_number : anydtdte12. ;
    4    date_as_string = put(date_as_number, mmddyy10.);
    5    result = catx("*", name, date_as_number);
    6    put result=;
    7    result = catx("*", name, date_as_string);
    8    put result=;
    9    datalines;

    result=Cora*8970
    result=Cora*07/23/1984
    result=Hannah*10404
    result=Hannah*06/26/1988
