===== SCREEN PAGE  =====

===== SYNTAX =====
     = SCREEN PAGE

==== PURPOSE ====


The semantics of this keyword is different, depending on whether double buffering 
is enabled or not. If double buffering is enabled, the ''SCREEN PAGE'' function
allows to know which page the program is on. There are two pages, page 0 (''PAGE 0'' 
or ''PAGE A'') and page 1 (''PAGE 1'' or ''PAGE B''). When you draw on page 0, 
page 1 is visible, and vice versa.

On the other hand, if doube buffering is not enabled, this function will return
the actual screen page in use, as set by ''SCREEN PAGE'' command.



==== EXAMPLE ====
    IF SCREEN PAGE = PAGE 0 THEN
       PRINT "first page"
    ENDIF


==== ABBREVIATION ====
   ScPg


==== AVAILABLE ON ====
  * TRS-80 Color Computer 3
