Hi there!

I'm try to load a file from Disc in ASM, but i have no success, my
latest Version (for test-reasons i use call&bb5a instead of write to the memory):

    ld hl,Testfile
    ld b,12
    ld de,Buffer
    call CAS_IN_OPEN
    jr nc,error

    call CAS_TEST_EOF
    jr nc,eof_found

    call CAS_IN_CHAR  ; "a" is everytime "Zero"!!! Why?   :(
    ;jp nc,check_eof      ; needed?
    call &bb5a
    jr read_one_char

    call CAS_IN_CLOSE

    cp 26   ; cp &e / cp &f ?!
    jr z,eof_found
    jp read_one_char

    call CAS_IN_ABADON

    defb "FC      .TXT"

Has someone an idea, what's wrong with the code?

Thanks & Bye



This is what i came up with which seems to be working with my ASCII files:

   org <wherever>

   ld b,12
   ld hl,testfile
   ld de,buffer
   call &bc77

   call &bc89
   jr nc,eof_found
   call &bc80

   push hl
   ld hl,buffer
   ld (hl),a
   inc (hl)
   pop hl
   ;; call &bb5a
   jr readchar

   call &bc7a
   defb "filename.ext"
   defb 0

Just note I'm reading the Text into the Buffer (wherever you decide to put it in memory), but I did test the output which appeared to be fine.

* Using the old Amstrad Languages :D   * with the Firmware :P
* I also like to problem solve code in BASIC :)   * And type-in Type-Ins! :D
