Keyboard Input in Assembly 8086 -

i'm trying create animation in assembly 8086, controlled keyboard, using ctrl , shift left , right.

i tried how recieve input keyboard in 8086, , how find out key pressed ctrl or shift (and generally, key pressed).

thank much!

are sure wouldn't rather utilize arrow keys left , right? problem command , shift don't "return" key, modify key pressed. handled in keyboard interrupt handler (9, iirc), , "hook" that. think easier in "bios info area" , watch interrupt handler keeps track of state of command , shift keys. seems me bda in segment 40h. keyboard status flags at... 17h , 18h? don't take word offsets, up. ralf brown's interrupt list. assumes "8086" means, like... antiquities. :)
