FRE

Returns the amount of available stack space, string space or memory.

Syntax

FRE(numeric_expression)

FRE(string_expression)

Comments

If the argument to FRE is -1, FRE returns the size in bytes of the largest array you can create. If the argument is -2, FRE returns the available stack space. For any other numeric argument, FRE returns the amount of available string space.

If the argument to FRE is a string expression, FRE compacts the free string space into a single block and then returns the available string space.

Example

PRINT "String space"; FRE("")
PRINT "Stack space"; FRE(-2)
PRINT "Array space"; FRE(-1)

String space 48460
Stack space 784
Array space 184092
