Macy HghTX45456 26/07/2009NA
Macy HghTX45456 02/08/2009NA
Macy HghTX45456 09/08/2009NA
Macy HghTX45456 16/08/2009NA

This is the code I have written

proc sort data-work.input;

by School_Name State School_Code;


proc transpose data=work.input out=work.inputModified;

by by School_Name State School_Code;


But I don't get the desired output the dates are actual variables when imported into sas the become _26_07_2009. Note there are about 185 dates and they are actual variables.

Pls Help

The variable _NAME_ will have the variable name and if your variables have labels _LABEL_ will have the the value of that label.  You can read _NAME_ using the INPUT function to create DATE.  _LABEL_ might contain a version of date that does not need to be translated.

17         data _null_;
18            _name_ = '_26_07_2009';
19            date = input(translate(_name_,' ','_'),ddmmyy11.);
20            format date date9.;
21            put _all_;
22            run;

_name_=_26_07_2009 date=
26JUL2009 _ERROR_=0 _N_=1
