Re: LOGO-L> About UCBlogo - out / in (port.exe)

[St_Vogel@t-online.de (Stephan Vogel)]

Hallo everybody!


Now I have written an improved file called "port.exe" in turbo-pascal, which 
works with both commands "out" and "in" in ucblogo.

You install the files in the following way:

-at first you copy the attached "port.exe"-file into the directory "ucblogo";
-then you copy both logo-files "out" and "in" (without postfix .lgo) into the 
subdirectory "logolib" of ucblogo.

Here the logo-files "out" and "in":
-------------------------------------------
to out :adresse :pin
shell (list "port "-w :adresse :pin)
end

bury "out

-------------------------------------------

to in :adresse
shell (list "port "-r :adresse)
openread "result.tmp
setread "result.tmp
make "result first readlist
setread []
close "result.tmp
output :result
end

bury "in 
-------------------------------------------

Now you can start the ucblogo and you write for example:

out 888 3 (LED 1 and 2 switch on)

In the second step you can write: 

in 888
 
You will get the value 3 of the printer port (lpt), which can operate with 
another function in mathematics (function value).


Best regards
