INVISIBLE attribute
The INVISIBLE attribute prevents user-entered
data from being echoed on the screen during an interactive statement.
Syntax
INVISIBLEUsage
The INVISIBLE attribute can be used for EDIT and
BUTTONEDIT fields, to hide characters typed by the end user, for example, to enter
a password.
Characters that the user enters in a field with the INVISIBLE attribute are not
displayed during data entry. Depending on the front end type, the typed characters are converted to
blanks, stars, underscores or dots.
The INVISIBLE attribute has no effect when displaying data directly to a field
with DISPLAY TO or DISPLAY BY NAME.
