3.40 cbm_k_ckout

Function

Designate a Logical File As the Current Output Channel

Header

cbm.h

Declaration

unsigned char __fastcall__ cbm_k_ckout (unsigned char FN);

Description

If you wish to output data to any device other than the screen, this routine must be called after OPENing the device, and before you output a data byte with the cbm_k_bsout() function. When called, the function will designate the logical file whose file number was supplied as the current file, its device as the current device, and its secondary address as the current secondary address. If the device on the channel uses the serial bus, and therefore requires a LISTEN command and possibly a secondary address, this information will be sent on the bus.

Limits

• The function is only available as fastcall function, so it may only be used in presence of a prototype.
