SYSTEM.TRIGGER_BLOCK
SYSTEM.TRIGGER_BLOCK represents the name of the block where the cursor was located when the current trigger initially fired. The value is NULL if the current trigger is a Pre- or Post-Form trigger. The value is always a character string.
Assume that you want to write a form-level procedure that navigates to the block where the cursor was when the current trigger initially fired. The following statement performs this function.
Go_Block(Name_In('System.Trigger_Block'));
