form.
Syntax
CLEAR FORM
Usage
The CLEAR FORM
instruction clears all form fields
of the current form. It has no effect on any part of the screen display except the form
fields.
Similar to CLEAR field-list
, the CLEAR FORM
instruction is
typically used when the program is not inside a dialog block execution controlling the form fields.
For example, after a database query with a CONSTRUCT
instruction, you might want to clear all search criteria entered
by the user with this instruction, to cleanup the form.
Note:
CLEAR FORM
clears the field values and resets the TTY attributes to
NORMAL
.The CLEAR FORM
instruction is usually not needed, if the program is always in
the context of a dialog controlling the form
fields.
Example
CONSTRUCT BY NAME sql
ON cust_name, cust_address, ...
...
END CONSTRUCT
CLEAR FORM
