If you set video memory larger than the required page size,
BASIC divides the assigned memory into pages based on the
page size requirement. For example, if you set aside 32K for
video memory for Screen Mode 1, BASIC divides the video mem-
ory into 2 pages ( 3 2 / 1 6 = 2 ) . See Chapter 8, SCREEN, and
PCOPY for more
on
video pages.
Note: BASIC allocates s t r i n g space dynamically.
BASIC displays a n "Out of string" space error if no
free memory is left for BASIC.
