Touch command attempt

Can you point me to what would be the cause that the returned error code is not printed, it's 0xEE (looking at the emulator)

[Zeal8bit]

The OPEN syscall returns the negated error on failure (As documented here https://github.com/Zeal8bit/Zeal-8-bit-OS/blob/main/kernel_headers/z88dk-z80asm/zos_sys.asm#L208)

So in your case you should use neg instruction in your label _touch_error. As such when it returns 0xEE, the returned error is ERR_READ_ONLY (0x18).

Seems like you tried to use touch on a file on the romdisk 😉

ok, then it's expected, as I was indeed doing that on romdisk
