You can calculate the Day of the Year number in C/SIDE by the difference between the date (in my example I use the current date defined by the operating system using the function TODAY) and the first day of year of the date using the CALCDATE function. You need to add 1 to the result to include the day of the date that you are using.
HOW TO calculate the Day of the Year number in C/SIDE
[sourcecode lang=”Cside”]
Number := TODAY-CALCDATE(‘<-CY>’,TODAY)+1;
[/sourcecode]
If you need it as Text you need to convert it using the FORMAT function
[sourcecode lang=”Cside”]
String := FORMAT(TODAY-CALCDATE(‘<-CY>’,TODAY)+1);
[/sourcecode]
