* DRAW WINDOW
'''Such a data block looks like this:'''
'''ATTENTION: ''' DR_WIN at &000B will switch the Interrupts OFF. The calling Task must switch them on again by itself.
'''To call this function:'''
Task number in TTNS3 = &BE03 (A Task can read its number from address TNUME = &7FFD)
'''Return from function: ''' First you need to take a look at the Z-Flag, then see for data in XL and XH.
Z-Flag set '1' -> User Break using ESC key! Do not use values in IX!
'''Return from function: ''' When returning, the zero flag provides information about the success:
Z-Flag cleared -> Areas overlapping! Area can NOT be used!
