Navigates to the navigable item with the next higher sequence number than the current item. If there is no such item, NEXT_ITEM navigates to the item with the lowest sequence number. If there is no such item, NEXT_ITEM navigates to the current item.
If the navigation is the result of a NEXT_ITEM (Tab key), item A and all items between A and B (in terms of their sequence number within the block, not in terms of their position in the block's navigation sequence) are validated. This can cause redundant validation. For example, if you use the Next Navigable Item property to establish a navigation sequence that is the reverse of the items' sequence within the block (as shown in the Object Navigator), then every time you hit tab, all items in the block (except the one you are tabbing to) will be validated. (In Form Builder 5.0, only item A is validated.)
The function of NEXT_ITEM from the last navigable item in the block depends on the setting of the Navigation Style block property. The valid settings for Navigation Style include:
PROCEDURE NEXT_ITEM;
Built-in Type restricted procedure
Enter Query Mode yes
none
/*
** Built-in: NEXT_ITEM
** Example: See NEXT_BLOCK
