Animatory state
Number denoting one of the phases of animation of a character's sprite.
Character buffer
Buffer containing data on the current state of a character.
Command list
List of commands used to control a character during a lesson.
Continual subcommand
One of various character-controlling command routines whose address is stored in bytes 124 and 125 of a character's buffer. The command is executed each time the character is moved - before the interruptible subcommand or primary command - unless the character is under the control of an uninterruptible subcommand (see 25126).
Interruptible subcommand
One of various character-controlling command routines whose address is stored in bytes 105 and 106 of a character's buffer. If present, the command is executed each time the character is moved, unless the character is under the control of an uninterruptible subcommand (see 25126).
Midstride
Of a character: in phase 2 or 4 of the walking animation. For example:

Primary command
One of various character-controlling command routines whose address is stored in bytes 99 and 100 of a character's buffer. If present, the command is executed each time the character is moved, unless the character is under the control of an uninterruptible or interruptible subcommand (see 25126).
SRB
Screen refresh buffer at 32524.
Uninterruptible subcommand
One of various character-controlling command routines whose address is stored in bytes 111 and 112 of a character's buffer. If present, the command is executed each time the character is moved, and overrides any other command (see 25126).
