Combining styles
You can combine several styles, by using the space character as a separator in the
   STYLE attribute.
In the following example, the STYLE attribute defines three different style
   names:
EDIT f001 = customer.fname, STYLE = "info highlight mandatory";
When several styles are combined, the same presentation attribute might be defined by different styles. In this case, the first style listed that defines the attribute takes precedence over the other styles.
For example, if the textColor presentation attribute is defined as follows by
   the info, highlight and mandatory styles:
infostyle does not definetextColor.highlightstyle definestextColorasblue.mandatorystyle definestextColorasred.
The widgets having a style set to "info highlight mandatory" will get a blue
   text color, because highlight is listed before mandatory.
