Chapter 3 Output Functions

There is one simple truth about output: everything that is the result of something else is output. And concordantly, anything that can be seen, heard, or understood is also output. Sometimes input is output:

Once upon a time there was a fly above a lake. There was a fish watching the fly that was thinking, ?When the fly comes near the water, I can jump up an grab the fly?. Well, their also happened to be a bear that was watching a fish that was thinking, ?When the fly goes near the pond, the fish will grab the fly and I can grab the fish?? The story goes on and on until a cat is watching a mouse watching a hunter?s sandwich; the hunter is busy watching the bear that is watching the fish that is watching the fly. This is an excellent example of output and its relation to input, and also how something can quickly change from input to output.

With that said, lets take a look at some ways we can use output to both request and display input on a screen. When you display input, it is called output This chapter is dedicated to dwelling even more on input and output. If you believe that you have a steady foundation in input and output philosophy, please feel free to skip ahead as this may seem unnervingly elementary.

Enter the program editor and press 3 to create a new program. Name this program ?Inputut?. Enter the program below as shown:

Exoutput()

w00t an update!

Look nice, now I see how it works and might help me if I want to mess around with BASIC if I get a 89. Al;so I now see why there are no word wrap in this function (I think): Basically on the 83+ on the home screen there are 8 row and 16 columns. Basically if you do Output(2,4,"HELLO" it will display HELLO at row 2 column 4. However the TI-89 output function is similar to the 83+ Text( command. If you do Text(12,31,"HELLO" it will display HELLO at pixel row 12 and pixel column 31 with no word wrap (text displayed outside of the screen to the right will be cut). This will display small text though. I dunno if there ar esimilar things on 68ks but on the 83+/84+ calcs (not on the 82/83 regular though) if you do Text(-54125+1,12,31,"HELLO" instead of Text(12,31,"HELLO" it will display big text fonts (like on the homescreen) instead of small ones

Unfortunately, there is no small font for the 68k's in pure Basic. You can use the Flib C library to achieve 3 font sizes (large, normal, small).

However, you get small font when using the Dialog Box function (like a pop-up window, it's neat) - but on the 92/v200 that font is also quite large. Bleh.

Yay! Got to go get the laptop and get it copied... B)

The font issue is remedied using the incrediblly powerful FLIB library.

Oh, ok.

Oh I see now the edited part of your post mjenkins86, very cool.

mdjenkins86 · « **Reply #73 on:** July 18, 2005, 03:40:00 am »

Some notes about the bonus program in chapter 3 for interpation:
the comand ord("A") will give you the "Ascii Key code" for the character "Capital A", which amazing is 65 like one would assume. Think C programming. The command char(65) will give the Ascii character for the code inputed. In this case the character corresponding with code 65 is "Capital A" or A. So the loop:

ord("A")c
For a, c,c+25
Disp char(a)
Endfor

Will display every letter of the alphabet in capital form.
This will do the same thing as

for a,65,91
Disp char(a)
EndFor

you would only do

ord("A")c

if you didnt know that "A" = 65
