When we created a stored procedure from sas eg using a code, we can create a propt by using utility,
For eg , if we create a Text, date or number type input promt, we can handle the value by using macro variable of same name as promt name.
Like if we create run_date prompt then we can us its value using &run_date.
So of i want to create a file or directory type of input for taking a xlsx file as input from input prompt, how that file need to be handled in code.
