How big can I make variables?

Single variables are easy...

Numbers can be 7 digits long, after that they are converted into #+## format, and lose their precision

Strings$, i am not sure, perhaps thousands long?

Arrays quickly loose memory
Single, up to (32000)
Double, up to (180,180)
Triple, up to (30,30,30)

Numbers are single precision floating point.

Arrays are limited to 32768 elements across all dimensions.

I just checked strings with this code. There doesn't appear to be a system limit besides clock cycles! I got the string length up to 2^24 before stopping the program. It took just shy of 16 seconds to concatenate the two strings prior at 2^23 each.

T$ = " "
TIME = TIMER
DO
  CLS
  PRINT ( TIMER - TIME ) / 60
  PRINT LEN( T$ )
  TIME = TIMER
  T$ = T$ + T$
LOOP

Strings are just null terminated C strings... I'm surprised I didn't put them a hard limit (like arrays). But usually they don't get so long, I guess...

The time it can take to process text can be a natural limiter....

For example, if one had the idea if using one string to represent a map of say 2000x1600, it would be 32x10^4

Here is a speed test... it takes time to build the data, but it displays quickly once made!

Use debug mode to monitor it building the map database...
