4D's technical support team can provide a wealth of knowledge on topics ranging from how to utilize certain features, to ascertaining potential bugs. For example, if you would like to understand how to insert date and time formulas in 4D Write Pro, or you think that the command CUT NAMED SELECTION may not behave as documented, 4D tech support can assist you.
However, tech support cannot help with specific code implementation, or comment on best practices for such implementations. For example, if you want to know how to design an output form that connects to your [Clients] table, or you would like critique on your code for implementing server-side scheduled processes, that would be out of scope for technical support. These types of questions would be more suitable for the 4D community at discuss.4d.com or 4D's Professional Services team.
