The K Command switches

The switches must follow the type and precede the file_or_map:

Kname type switches file_or_map

If any switches follow file_or_map, they will be silently ignored.[3] All switches begin with a - character and are listed in Table 23-3. Note that some database-map types utilize only a small subset of all switches (e.g., dequote uses only -a, -D, -s, and -S, and sequence doesn’t use any).
