The ReadBias attribute specifies the bias setting for a field when the CurMode attribute for the frame is set to FM_READ.
If you set this attribute at a time when the CurMode is something other than FM_READ, it is not enforced until the CurMode setting is changed to FM_READ. If you set the CurBias attribute when the CurMode is FM_READ, this attribute is changed. If the field is a composite field, setting this attribute affects the children as well (see
CurBias Attribute (see
CurBias Attribute) for details).
The valid settings are the same as for
CurBias Attribute (see
CurBias Attribute).
