COLORREPL()

Syntax:     COLORREPL(<attr1>[,<attr2>])

Arguments:  <attr1> denotes the new attribute(default: standard attribute
            CLEARA).
            <attr2> contains the attribute to be changed.

Returns:    A character string.
            A null string is returned.

Usage:      COLORREPL() can simplify screen handling.  With this
            function it is possible to exchange all <attr2> attributes with
            <attr1> attributes.  The color of all input fields can be
            changed after a read, presuming that they have a specific
            common attribute.  It is then easy to make it known that
            these fields are no longer active.

Notes:      If the <attr1> argument is not specified, all screen attributes
            will be exchanged for the <attr2> attribute.  If the <attr1> is
            also missing, then the CLEARA default attribute will be used.

Library:    CT1.LIB
