I need to be able to create a custom function within Crystal that will query a file and then perform calculations on the results returned by the query.
Specifically, I need to create a function that will read a date from a file and then calculate various date ranges based on the date in the file.
First, is this even possible within Crystal?
Secondly, if so, could someone post sample code?
Thanks in advance.
