I'm having problems with the Maximite PRINT @(x,y) command. Running the program:

Quote CLS
LINE (0,0)-(45,8), , B
PRINT @(0,0), "X"
LOCATE 0,0: PRINT "O"

prints a box 45 pixels by 8 starting from the top right hand corner as expected but the "X" is printed just to the right of the box NOT in the top right hand corner where I expected it to be printed. The LOCATE command DOES cause the "O" to be printed in the top right hand of the screen.

I drew the box just to get an idea if how big the x offset is.

Am I doing something wrong or is this a bug? This is version 4.5 (not 4.5C) but I see no mention of this problem.

Thanks
Bill

I don't know if it's intended, but in the data sent to a terminal, there is a <TAB> chracter just before hte 'X'

Quote CLS
'LINE (0,0)-(45,8), , B
PRINT @(0,10), "X"
LOCATE 0,40: PRINT "0123456789"
END

Thanks Jim,

That would do it. I'll stick with the LOCATE command for now and hope Geoff fixes it with the new version.

What version of CMM MMBasic are you using?

Oh, I wasn't aware that Geoff had released anything on the Maximite since 4.5C. I can't find any mention of it.

Thanks Jim,

I guessed that was the case. If it is a pre-release of the new version based on the Micromite software can you please report the problem to Geoff in case he doesn't see this?

Bill,

The problem may be in your syntax of the PRINT @ command.

According to the manual, there is no comma between the co-ordinate argument and the printable data. That is, the comma is causing the actual position to effectively be one tab position further out ( as Jim indicated ).

Thus, your program should be :-

CLS
'LINE (0,0)-(45,8), , B
PRINT @(0,10) "X"
LOCATE 0,40: PRINT "0123456789"
END

Note there is no comma between PRINT @(0,10) and the data argument "X" (I think MMBasic ignores the space).

... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

Thank you Panky,

You are right of course. That IS the problem. I don't know where the comma came from, I swear I did RTFM several times and still didn't pick it up. Proves once again the value of the forum.

Sorry to waste everyone's time

I suppose it looks a little like:
PRINT #1, "something"

where every BASIC I've met requires the comma, which has the advantage that if you wanted to:
PRINT #1, -X, -Y

it works as expected, whereas if the comma wasn't required:
PRINT #1 -X, -Y

would be likely to try to print to channel 1-X
