17 Algorithm definitions
Each of the 17 algorithm definitions holds a 36 byte program definition (17
* 36 = 612 bytes). The 1st entry is the latest parameter settings for
algorithm 0, the 2nd entry is the latest parameter settings for algorithm 1,
etc. See Program Definitions for the structure of each of the 17 algorithms.
The GSP7 uses this table while changing a program's algorithm.
