Store array information in extended memory (128kb)

[rbiondi]

Hello,

Is it possible storing arrays and/or Strings in Zx Spectrum Extended Memory (128kb)? 
How could this would be accomplished?

Thank you very much!

write data into bank 1, 3 and 4.

switch to the bank and always get the data from $c000.

the data from the bank is always in $c000.

Code:

#Include <SP/Fill.bas> #include <memcopy.bas> DIM wert AS UInteger Sub fastcall _bank(n as UByte) ASM   ld c, a  ; A register contains the n parameter   ld a,(0x5b5c)   and 0xf8   or c ;bank N auswählen   ld bc,0x7ffd   di   ld (0x5b5c),a   out (c),a   ei END ASM end sub CLS _bank(3) for wert=$c000 to $c000+6143   poke wert,129 next wert _bank(4) for wert=$c000 to $c000+6143   poke wert,255 next wert _bank(1) for wert=$c000 to $c000+6143   poke wert,137 next wert do     IF INKEY$ = "q" THEN       _bank(1)       MemMove($c000, $4000, 6144) end if IF INKEY$ = "w" THEN       _bank(4)       MemMove($c000, $4000, 6144) end if IF INKEY$ = "e" THEN       _bank(3)       MemMove($c000, $4000, 6144) end if  loop

You can also get the data from $c000 and bring it to $c000 with poke/peek.
