Restoring Data with a variable

If the speed is a critical issue, you can load all the levels data in a 2D array at the starting of the program; later, read the values for a level from the array itself.

Suppose you have 1000 values to be red for each level, and 100 levels.

Then you can dimension an array like

CONST terminator = -999 ;level data terminator
dim level(100,1000)
;fill the array with level data, and terminator
read_all_the_levels_data_into_the_array()

;and read the values for the level number 'L' with this:
for n = 1 to 1000
generic_value = level(L,n)
if generic_value = terminator then
exit
endif
next
