A82: Re: arrays and random numbers
If you want to define a matrix, just define a list of bytes. To define a
4x4 array you could do the following :
Matrix:
Q1:
.DB 0,0,0,0
Q2:
.DB 0,0,0,0
Q3:
.DB 0,0,0,0
Q4:
.DB 0,0,0,0
So if you wanted to set element 2,2 to 3 you could do the following :
LD A,3
LD (Q2+1),A
If you want to set element H,L to A you could do the following :
CALL MUL_H_L ; This function is placed in the rom, but i could not remember
what i is usually called. HL=H*L
LD DE,Matrix
ADD HL,DE ; HL points to element
LD (HL),A
The easiest way to make random numbers is to use the R register, but this
does not give very random numbers. On ticalc you can find source code for
functions which uses both methods.
