Loops, loops and … more loops!

Automatically translated from English

Like many other programming languages, 4D provides the ability to iterate over numbers with a For(…) / End for statement, or over a condition thanks to the While(…)/End while and Repeat/Until(…) keywords. These iterations (or loops) are very useful, but not the most appropriate way to iterate over advanced data types such as collections and entity selections. That’s why the new For each(…)/End for each iterator has been created, to help ease your coding!

Log files can be extremely useful for troubleshooting. They’re also a big help for finding the root cause of an incident. Logs let us track of where a problem occurred, and when. Before, with the Get 4D folder command, you could easily access the folder containing all the logs.
