Usage / DIALOG control blocks |
The AFTER DIALOG block is executed one time as the last trigger when the DIALOG instruction terminates, when performing an ACCEPT DIALOG instruction. Dialog finalization code can be implemented in this block.
The dialog terminates when an ACCEPT DIALOG or EXIT DIALOG control instruction is executed. However, the AFTER DIALOG block is not executed if an EXIT DIALOG is performed.
If you execute one of the following control instructions in an AFTER DIALOG block, the dialog will not terminate and it will give control back to the user:
In the next example, the AFTER DIALOG block checks whether a field value is correct and gives control back to the dialog if the value is wrong:
ON ACTION accept ACCEPT DIALOG ... AFTER DIALOG IF NOT cust_is_valid_status(p_cust.cust_status) THEN ERROR "Customer state is not valid" NEXT FIELD cust_status END IF
