[Gambas-user] array size limitations relative to available RAM and swap space

[kevinfishburne]

Using GAMBAS 2.19 I tried creating an array:

PUBLIC Elevation AS Short[65536, 65536]

With no data assigned to any of the array's elements, reading Elevation[0,0]
shows a value of 24. I'm thinking it should be zero. Reading
Elevation[4095,0] crashes the program. I tried reading Elevation[100,100]
from the debug window and it also crashes the program.

Granted this array if fully allocated would consume 8 gigabytes of RAM. My
system has 4 gigs of RAM and an 8 gig swap file. Does GAMBAS use the swap
file if enough physical RAM isn't available? What are the size constraints
of arrays? Why would Elevation[0,0] show up as 24 when Elevation[1,1], etc.,
are zero as they should be?
