Doesn't Seem to be Any Programing Languages for AOS4 for the Average Person

You see, I cannot get to grips with this
closeWindow()

Why are those brackets there? Why isn't a variable inbetween them?

To me
char *str1;
means multiply "char" with "str1".

ptr=$1000
Rem read one byte form address ptr+0
Print "Get value of peek ="; Peek(ptr+0)

char *ptr;
ptr=0x1000;
/* Read one byte from address n+0 */
printf("Get value of peek = %d\n",ptr[0]);

#include <stdlib.h>

int main()
{
char *ptr;
// reserves 100 bytes at any address
ptr = malloc(100);
printf("Get value of peek = %d\n",ptr[0]);
// frees 100 bytes after use.
free(ptr);
}

MODULE '*athiest'

PROC main()
openWindow(320, 200)

Plot(159, 99, 2)

waitForUserToCloseWindow()
closeWindow()
ENDPROC




OPT MODULE, EXPORT
MODULE 'intuition/intuition'
DEF window

PROC openWindow(width, height, x=0, y=0, title=0)
window := OpenW(x, y, width, height, IDCMP_CLOSEWINDOW, WFLG_CLOSEGADGET OR WFLG_ACTIVATE, IF title THEN title ELSE 'window', NIL, 1, NIL)
IF window = NIL
PrintF('ERROR -- Could not open window!\n')
Raise("WIN")
ENDIF
ENDPROC

PROC closeWindow() IS CloseW(window)

PROC waitForUserToCloseWindow()
WHILE WaitIMessage(window) <> IDCMP_CLOSEWINDOW
ENDWHILE
ENDPROC

I don?t know what you?re trying to do whit the last line; I think a structure might be better.
A structure is a way to group variables.

Struct
{
char *str1;
char *str2;
int value1;
int value2;
char *str3;
} my_value_type;

I have made a 4 dimensional array in AMOS, as well as many many other arrays and have no problem whatsoever manipulating them.

Hi LiveForIt,

You lost me.

ptr=0x1000

"x" isn't a number?!? The more I see, the less "normal" it all becomes.

That is a lot to expect from a person that wants to change the colour of one pixel!!!

That's the way Hollywood (and LUA) handle data, somithing similar to standard structures:

mytable = { 2, 3, "four" }

is the same as
mytable[0] = 2
mytable[1] = 3
mytable[2] = "four"

you can have non-numeric indexes to simulate structures:
mytable = { name = "Johnny", surname = "Mnemonic" }

so you can access them with:
mytable.name
mytable.surname

Of course, that's not a complete example, which would be more like this:
// Compile with gcc -o pixelplot pixelplot.c -lauto

#include <proto/intuition.h>
#include <proto/graphics.h>

int main(void)
{
struct Window *window;

window = IIntuition->OpenWindow(NULL);
IGraphics->WritePixel(window->RastPort,0,0);
}

Which is obviously completely ridiculous, as the pixel plotted will end up over the window border (if it has a border, which we can't know for sure), we don't know what colour it will be, and the whole caboodle is left on screen after the program exits.

Semi-colons denote the end of an actual line of code, which can be multiple lines long.

Hi Hans,

Reading the above, therefore:
Quote:

this is C:

if( x == 10)
{
drawCar();
}
else
{
drawPig();
}

to me becomes (and can only make sense) by your own rule:


if( x == 10){drawCar();
} else { drawPig();
}

And that last bracket seems to be missing the semi-colon. This is why I can not understand C. I can not understand why there isn't a semicolon to the right of the final bracket??

As for making the variables global, that's because I almost always need access to all of them at any given time.

P.S. What about "Return 0;". Isn't there always a "return 0;" (why, I don't know, more useless junk) at the end?
