reading a file from disc with asm

[Fran123]

Hello

I want to do a loader calling |cpm, then when the code is executing, I try to read a file from disc with this code:

Code Select Expand

;; in
;; hl - name
;; b - name length
;; de - destinatin address memory
load_bin:
call &bc77 ;cas in open
ex de, hl
call &bc83 ;cas in direct
call &bc7a ;cas in close
ret
but, when I execute I get "Press PLAY then any key:"

What is happening?    I'm following the book of DATA BECKER   (https://cpcrulez.fr/book_german-floppy_buch.htm)

I'd have to look up the disc routines to really help you but my first observation is that the routines you're calling are cassette routines.

It seems when you type |cpm roms are deactivated :/

Disk Rom is also disabled after a normal run"Test" you have to reenable it afaik ....
