PCB-00234: FOR variable "string" is invalid type..

Answer / guest

Cause: The count variable in a FOR clause has the wrong
datatype. The datatype must be NUMBER or LONG (or be
compatible with NUMBER or LONG).

Action: Check the declaration and check that the count
variable has a datatype of NUMBER or LONG (or a compatible
Oracle or host-language datatype).
