|
|
* Any string expression returns the size, in bytes, of free string storage space.
|
|
* Also compacts the free string storage to a single block of memory.
|
|
* 0 returns the same value as using a string expression above.
|
|
* -1 returns the size of the largest non-string array in bytes that could be dimensioned.
|
|
* -2 returns the amount of stack space, in bytes, available to a running program.
|
|
* Any other numerical value returns the size of the next block of string memory storage space.
