At runtime, you can use ui methods to find out and change the property value (so as to make the input text visible or masked):
LET widget_var = ui.<widget>.ForName("widget_id1")
CALL widget_var.setInvisibleValue(...)

4gl code sample |
DEFINE tf_1 ui.TextField ... LET tf_1 = ui.TextField.ForName("f1") CALL tf_1.setInvisibleValue(0)
|
DEFINE tf_2 ui.TextField ... LET tf_2 = ui.TextField.ForName("f2") CALL tf_2.setInvisibleValue(1)
