READONLY Mnemonic - Make Edit Control(s) Read-Only
Syntax
'READONLY'(id{,id...})
Description
For BBj-specific information, see READONLY Mnemonic – BBj.
The 'READONLY' mnemonic (Visual PRO/5 Rev 3.12 or later only) makes one or more edit, custom edit, InputE, or InputN controls read-only. The user can highlight the contents of a read-only edit control with the mouse and copy it to the clipboard, but cannot change it. Making a control read-only does not change its foreground color. If the control has a customized background color, making it read-only will not change it. The background color of controls that do not have a customized background color will change from the default window background color to the default 3D objects background color in accordance to a Windows standard color scheme. Read-only edit, custom edit, InputE, and InputN controls can be made user-editable with the 'READWRITE' mnemonic.
