GOTO (arithmetical expression) - JBGV - 05-09-2011

Hello!

Could anyone tell me how I can simulate "GOTO (arithmetical expression)":

ex:

Code:
N can have a value between 1 and 20

GOTO (1000+(N*10))

I need to assign values to an array depends on the value "N", I had thought something like this:

Code:
ASM

ORG 62000

DEFB 12,5,8,11,12,11,4,11,(...)       

END ASM

DIM P(7) AS UBYTE

...

N=20

...

FOR B=0 TO 7

P(B)=PEEK (62000+N+B)

NEXT B

Is this efficient?

Is there a danger that the program itself erase the data stored at positions 62000?

THANKS

Line numbers? this is stone age! just make a buffer and calculate the offset to copy the data from memory to variable array.

pseudocode, as I'm at work now:

Code:
address=@labelofdata+size*n

copymemory(address,@p(),size)

There is a include for copymemory...
This if efficiency! GoTo calculation was working only in HiSoft Basic compiler, but you had do define all possible lines for calculated jumps with REM: GOTO directive. With more programming experience there is absolutly no need for calculated goto.

Copymemory, Thanks ¡
