CONTINUE INPUT instruction
CONTINUE INPUT
skips all subsequent statements in the current control block and
gives the control back to the dialog. This instruction is useful when program control is nested
within multiple conditional statements, and you want to return the control to the dialog.
If this instruction is called in a control block that is not AFTER INPUT
, further control blocks
might be executed depending on the context.
CONTINUE INPUT
instructs the dialog to continue as if the code in the control
block was terminated ( it's a kind of GOTO end_of_control_block
). However, when
executed in AFTER INPUT
, the focus returns to the current row and current field in
the list, giving the user another chance to enter data in that field. In this case the
BEFORE ROW
and BEFORE FIELD
triggers will be invoked.
ON ACTION
block gives control back to the dialog, skipping
all subsequence instructions of the ON ACTION
block:ON ACTION zoom
IF p_cust.cust_id IS NULL OR p_cust.cust_name IS NULL THEN
ERROR "Zoom window cannot be opened."
CONTINUE INPUT
END IF
IF p_cust.cust_address IS NULL THEN
...
Use the NEXT FIELD
control
instruction to give the focus to a specific field and force the dialog to continue. However, unlike
CONTINUE INPUT
, the NEXT FIELD
instruction will also skip the
further control blocks that are normally executed.
