Par2: MASK a single control
2002-08-02 -- Richard Taylor
 
The MASK attribute on individual controls was never actually implemented (although it was supposed to have been). To do what you want, leave the ENTRY control you want to mask out of the WINDOW structure and, after the OPEN(Window) statement turn on PROP:Mask for the window then CREATE the ENTRY control. MASK operates only on controls created after it becomes active. That means that if you place the attribute on the WINDOW structure, all controls in the structure are affected. If you leave it off, then turn it on in code using PROP:Mask, only those controls you explicitly CREATE after turning it on are affected.
