This code just maps command strings into integers for easier use with the
switch() statement elsewhere in the file. The list of names/numbers is
pregenerated in include/parrot/debug.h. See the section starting:
/*
* These constants correspond to the debugger commands and are
* used in src/debug.c. To map command strings to their
* numeric values, use the algorithm from parse_command() in that file.

#define c_b 25245
