ALPHA subroutines provide protection against inadvertently overwriting data read from the input file. In this section, we describe how to modify the internal ALPHA banks (QVEC and QVRT) intentionally. For ``standard'' operations (creating new tracks, vector operations, Lorentz transformations, etc.), ALPHA utility routines are available (see ch. 9). The tools described here can be used when standard utilities do not exist.
