From what I can tell, this program does exactly three things:
• preparing the initial high score list
• writing default settings to HUUMA.CFG
• and allocating the game's resident configuration structure and writing its
segment address to bytes 6-7 of HUUMA.CFG
All that results in a COM file of 6.84 KiB, 83% of which is library code.
That's why C was once seen as a bloated high-level language as well.
