Re: [Bug-apl] location of cursor on new apl session

[enztec]

∇Hi

wow
/usr/local/bin/apl 
)host stty echo icanon 

is the magic !!!   thanks

pure scripting also works but with no 'workspace benefit' 

the --rawCIN command line option is listed in the newest apl.html that comes 
with sources and on the site but is not in    man apl   (apl.1)

⍝ thanks very much   ∇
