Answer:
- Prior to starting the application, if the environment variable SET BTRPARMSCHK=Y is specified, the status 1015 is returned.
- Isolation of errors that are caused by passing invalid pointers to Btrieve is done by using this environment variable.
- Once this variable is set, Btrieve performs the validation on pointer parameters that are passed in to READ/WRITE access on certain ranges.
- Btrieve validates position block pointer on the range of 128 bytes, length pointer validates on two bytes and data buffer is validated on 255 bytes for key buffer
