ATTRIBUTE
The ATTRIBUTE clause assigns visual attributes in some 4GL statements.
Keywords listed at the left of this diagram specify color; those at the right
specify intensity.
The ATTRIBUTE clause can appear in the following statements:
CONSTRUCT
| DISPLAY FORM
| INPUT ARRAY
|
DISPLAY
| ERROR
| MESSAGE
|
DISPLAY ARRAY
| INPUT
| PROMPT
|
Besides these statements, both the OPEN WINDOW statement and the OPTIONS
statement can include ATTRIBUTE clauses that support additional keywords.
An attribute clause in any statement except OPEN WINDOW or OPTIONS can specify
zero or more of the BLINK, REVERSE, and UNDERLINE attributes, and zero or one
of the other attributes. That is, all of the attributes except BLINK, REVERSE,
and UNDERLINE are mutually exclusive.
The BLINK and UNDERLINE attributes have no effect in Windows, but are included
for compatibility with 4GL programs written for character-based environments.
