Difference between day program runs and variable date in dataset.

I currently have a data set that shows dates different actions have happened.  I am trying to figure out the number of days since that date based on the day the program is ran.

 

open_dt, ocfr_dt, lwsi_dt, pcse_dt, pcna_dt, close_dt

 

I have a column that has the status based on which date is filled in.  Based on the status I need it to subtract that subsequent column from the date the pgroam is run.

I delcare the variable today at the top.

data _null_;
today=today();
call symput('today', put(today,date9.));
run;

and I wrote it like this but get a syntax error.

 

data fraud_ovrvw4;
set fraud_ovrvw3;
if frd_status = 'Support Requested' then updt_tm = (lwsi_dt - &today.);
run;

I am not sure the syntax to get updt_tm to tell me how many days between the column_name I want it to look and the day its ran.

  set fraud_ovrvw3;
  if frd_status = 'Support Requested' then updt_tm = (lwsi_dt - today() );
run;

That is what I tried the first time and the column updt_tm comes back blank.  Does it matter the format, as the date in the data set is ddmmmyyyy

Did you get an error?

Format shouldn't matter, but the type does, is it a character or numeric variable?

The format doesn't matter. If it comes back missing then the input value is missing too.

Which type (numeric, character) is

lwsi_dt

and what values do you find when you inspect your input dataset?
