Function and Edit Keys

PRO/5 considers a terminal to have two groupings of loadable keys on the keyboard. This requires two different mnemonics to reference the different groups. The 'FL' mnemonic specifies that you are dealing with the function keys. These are the keys normally labeled with either 'F' or 'PF'.

The 'EL' mnemonic specifies that you are dealing with the keys outside of the 'function' keys. These keys would include cursor keys and edit operation keys, and are referred to here as "edit keys."

Either of the key load mnemonics is followed by a parameter string that contains a function code and any additional parameters required for that function. The function code must be the first byte of the string.

For the UNIX operating system, the function and edit key numbers used to identify the keys to be loaded are as follows:

Hexadecimal Key Numbers	Function key as defined by termcap (use with 'FL' mnemonic)
00 - 09	F1 through F10
0A - 13	Shift + F1 through F10
14 - 1D	Control + F1 through F10
1E - 27	Alt + F1 through F10

Decimal

0-31 Termcap keys k1 through k9, k0, kA through kU

Hexadecimal Key Numbers	Edit keys as defined by termcap (use with 'EL' mnemonic)	Termcap
00	left arrow	k1
01	right arrow	kr
02	up arrow	ku
03	down arrow	kd
04	Home key	kh
05	End key	EN
06	Page Up	PU
07	Page Down	PD
08	Insert	IN
09	Delete	DL

For MS-DOS without an extended keyboard, the function and edit key numbers used to identify the keys to be loaded are shown below. The configuration file alias line that defines the terminal must NOT contain "ekb" in the MODE= statement. See PRO/5 Workstations Under MS-DOS and MS-DOS Networks in the Installation and Configuration Guide for more details.

10 - 19	Shift + F1 through Shift + F10
20 - 29	Ctrl + F1 through Ctrl + F10
30 - 39	Alt + F1 through Alt + F10

For MS-DOS with an extended keyboard, the function and edit key numbers used to identify the keys to be loaded are shown below. To use the extended keyboard, the configuration file alias line that defines the terminal must contain "ekb" in the MODE= statement.

Hexadecimal Key Numbers	Function keys as defined by termcap (use with 'FL' mnemonic)
00 - 11	F1 through F12
12 - 23	Shift + F1 through Shift + F12
24 - 33	Ctrl + F1 through Ctrl + F12
34 - 43	Alt + F1 through Alt + F12

58	Alt + Enter (Numeric keypad)
59	Alt + Esc
60	Shift + Tab
61	Ctrl + Tab
62	Alt + Tab
63	Alt + Backspace
64	Alt + Enter (Character keypad)
65	Ctrl + Print Screen
66	Numeric keypad 5 (Without NumLock)
67	Ctrl + 5 (Numeric keypad with or without NumLock)

In addition, for MS-DOS with or without MODE="ekb", the Alt of any printable key (shifted or unshifted) may be loaded using the 'EL' mnemonic and adding 128 to the decimal ASCII value of the character printed by the key. For alphabetic characters (A - Z), add 128 to the decimal ASCII value of the upper case character. For all other printable keys, add 128 to the decimal ASCII value of the unshifted character printed by the key. For example, since the decimal value of "A" is 65 and 65 + 128 = 193, a PRINT 'EL' statement with key 193 will assign a string to both Alt + A and Alt + a. Since the decimal ASCII value of "4" is 52 and 52 + 128 = 180, a PRINT 'EL' statement with key 180 will assign a string to both Alt + 4 and Alt + $.
