This document describes using simh to emulate APL\1130 on the IBM 1130

uses Disk Monitor System Release 2 Version 12

ibm1130 job lisptest    generates lisptest.lst

run ibm-apl-1130.sh to run ibm 1130 with apl

telnet localhost 1130

konsole seems to work the best as a terminal emulator
use iso 8859-1 encoding with APL 2741 font

[ is mapped to APL left arrow
not all characters show up correctly but they still work
e.g. shift 2 g is delta but it isn't visible

console keys
------------

Note that the printing computer terminal (IBM 2741) has a different
keyboard layout compared to the main IBM 1130 console
 
use number shift 3 to get numbers

uio -> 123
jkl -> 456
m,. -> 789  

. is .
, is ,
4 is +
5 is multiply
= generates ! which gives character error
;' generates []

hitting 2 twice locks shift 
using shift (hit 2 once for one character shift)

4 becomes minus
5 becomes divide
9 becomes backspace
T becomes tilde ~
P becomes asterisk * (exponent)
J becomes small circle
K becomes '
E becomes epsilon
F becomes _ (flat line)
I becomes iota
G becomes del (not visible)
L becomes quad (not visible)
R becomes rho
;' becomes ()
, becomes ;
. becomes :
- becomes ATTN (Attention)
Q becomes ?
M becomes absolute value

backspace is cumbersome, one must hit 9 to backspace then minus (ATTN)

hitting 3 twice locks number shift
using number shift (hit 3 once for one character number shift)

asdfghjkl; becomes 1234567890
P becomes and
E becomes <
U becomes >
T becomes =
Z becomes /
C becomes \
, becomes !
W becomes high minus
I becomes not equal
B becomes reversal
N becomes reversal along first axis
M becomes transpose
[ becomes natural log

regular keyboard shift (not the same as using 2 or 3)

, becomes multiply
8 becomes +
f1 becomes divide (does not work)

apl statements
--------------

~0        not zero returns 1
~1        not one  returns 0
divide 2  returns reciprocal of 2
!4        returns factorial of 4
2*3       returns 2 to the power of 3
*3        returns e to the power of 3
4+4       returns 8
5x5       returns 25
16* divide 2
          returns the square root of 16 which is 4
'this is a test'
| negative 2 
          returns absolute value of negative 2 which is 2
iota 10   returns numbers 1 to 10

functions
---------

del test
[1] 'this is a test'
del           defines function test

del test
[1] [quad]    lists entire function

[1] [1.5]     inserts a line between line 1 and line 2

[4] attn enter
              deletes line 4, attn is -

del test del  delete function test
              
doesn't have
