ERASE arrayname [,arrayname]...

arrayname	The name of an array.
For static arrays, ERASE sets each element of a numeric array to zero and each element of a string array to null.
For dynamic arrays, ERASE frees the memory used by the array. You must redeclare the array's dimensions with REDIM or DIM before using it.


DIM a%(0)
a%(0) = 6
PRINT "Before: "; a%(0)
ERASE a%
PRINT "After: "; a%(0)
