INVISIBLE attribute

The INVISIBLE attribute prevents field data being readable on the screen.

Syntax

INVISIBLE

Usage

The INVISIBLE attribute can be used for EDIT and BUTTONEDIT fields, to obfuscate the value of the field. A typical usage of INVISIBLE is for password entry fields.

Depending on the front-end type, the characters are converted to blanks, stars, underscores or dots.

Characters that the user enters in a field with the INVISIBLE attribute are obfuscated during data entry. When displaying data by program to a field (with DISPLAY TO / BY NAME or when the interactive dialog synchronizes the form field content with the program variable), the INVISIBLE attribute will also make the field content unreadable.
