The Prizm's syscalls and related keyboard functions use different methods of representing keys. These values vary in size and are tied to specific groups of syscalls. The Reading Input tutorial page has information on such syscalls and their uses.

The matrix key codes are a 2 byte column/row pair specified as 0xCCRR. These correlate to the column and row of the keyboard matrix that the key is located at. The following functions use this key format:

The two tables in this section show the same information, presented in different ways.

The key codes here are decimal values made up of the column and row as CR. The following functions use this key format:

Character and Control Codes

Character codes are not directly mapped to the physical keys on the keyboard. The values use the state of key modifiers to return a value pertaining to the specific function of a key (pressing EXIT returns a code that's different from when pressing SHIFT then EXIT). The following syscalls use these codes:

The values in the tables below are in hexadecimal.

Notes

  • The values of the characters in Alpha mode are the same as their ASCII codes, both for upper- and lower-case.
  • Certain keys have a different value when modifiers are on, even when there is nothing printed on the keyboard to indicate such. Examples include Shift+Optn and Shift+cursor keys.
  • Control codes start at 0x7530 (decimal: 30000) and are meant to be redirected to syscalls such as EditMBStringCtrl; character codes are much lower values and should be redirected to syscalls like EditMBStringChar.
