NPC reads computer screen for PC

A repost, as I found this board a more suitable place:

NPC reads book for PC, but doesn’t help PC using computer console. I want to make NPC read screen for PC.

In game.cpp, the function use_computer checks illiteracy, blindness, near-sightedness, but I don’t understand the read function. Where does read function checks illiteracy and let nearby NPC help? I want to add that to use_computer.

Blind people CAN use computers!

Both my mom and my god father are blind, and my god father can make ANY computer go into blind people mode and talk to him.

That’s talent!
