Form and subform communication made easy!

Starting with 4D v19 R5, the ability to associate a variable with a subform has enriched the possibilities of interfaces and communication between forms and subforms. The means of communication are now simplified by two new commands: Say hello to OBJECT Get subform container value and OBJECT SET SUBFORM CONTAINER VALUE.

A Seamless Way to Manage Parameters

In the declaration of a function or method, you explicitly define its parameters. Then, when calling that function or method, you can pass fewer parameters to it if some are optional. Or, if you used the declaration with ${n}, the number of passed parameters is variable. In this case, you use the Count Parameters command with a loop over the arguments. This code works flawlessly. Still, it’s a little bit heavy.

You asked us for a lighter way to handle parameters, and we listened. Starting with 4D v19 R5, we provide you with a new command, Copy parameters, allowing you to write a seamless, more elegant, and easier-to-read code.
