; NAME:
; SKEY_MIPS
;
; PURPOSE:
; Under Unix, the number of function keys, their names, and the
; escape sequences they send to the host computer vary
; enough between various keyboards that IDL cannot be
; written to understand all keyboards. Therefore, it provides
; a very general routine named DEFINE_KEY that allows the
; user to specify the names and escape sequences. This
; routine uses DEFINE_KEY to enter the keys for the MIPS RS
; series keyboard.
;
; Note: SKEY_MIPS is primarily designed to be called by
; SETUP_KEYS, which attempts to automatically detect the correct
; keyboard type in use, and define the keys accordingly.
; Nonetheless, SKEY_MIPS can be called as a standalone
; routine.
;
; CATEGORY:
; Misc.
;
; CALLING SEQUENCE:
; SKEY_MIPS
;
; INPUTS:
; None.
;
; KEYWORD PARAMETERS:
; APP_KEYPAD: Defines escape sequences for the group of keys
; in the numeric keypad, enabling these keys to be programmed
; within IDL.
;
; NUM_KEYPAD: Disables programmability of the numeric keypad.
;
; OUTPUTS:
; None.
;
; COMMON BLOCKS:
; None.
;
; SIDE EFFECTS:
; The definitions for the function keys have been entered, and
; can be viewed using HELP,/KEYS .
;
; The <Print Scrn>, <Scroll Lock>, and <Pause> keys are not defined,
; as they do not generate standard escape sequences. The same is
; true for <Home>, <Delete>, and <End> in the grouping of six keys above
; the arrow keys; however, the other three in the group ARE defined.
; Keys defined to have labels beginning with a capital "K" belong
; to the numeric keypad group. For example, "K9" refers to keypad
; key "9". The <Num Lock> key is the only one within the keypad
; which is not defined.
;
; MODIFICATION HISTORY:
; TJA , July 1990. SETUP_KEYS_MIPS created, and call to SETUP_KEYS_MIPS
; placed in procedure SETUP_KEYS.
; AB, 21 September 1992,renamed from SETUP_KEYS_MIPS to SKEY_MIPS to
; avoid DOS filename limitations.
; AB, 16 June 1993, The IDL scanner used to treat octal string escapes
; in a manner similar to the C language, but this ability was
; removed to make the MS DOS port possible (conflicts with
; file path specifications). Removed all uses of that here.
