Any one know how to program
"EJECT" the cd-rom for PBdos 3.5.

Hi Han,

If you're not familiar with Ralf Brown's interrupt list yet, check
it out. It's a life-saver:

You'll need to learn how to execute assembly routines to use this. Check
your power basic manuals for instructions on how to do this.

Cheers,
Jerry

You don't need assembly language to call interrupts using PB/DOS.

The function you need is called (believe it or not!),"CALL INTERRUPT"

Be aware, however, that loading the registers can sometimes be
a real bugger. Load them carefully!!

Han,
the following appears to work in PB3.5 running in a Win98 DOS box.

Paul.

%AX=1:%BX=2:%CX=3:%DX=4:%SI=5:%DI=6:%BP=7:%DS=8:%ES=9:%FLAGS=0
 
reg %AX,&h440d
reg %BX,10          'This is the drive to eject where Drive A=1,B=2,C=3 etc. My CD is Drive J = 10
reg %CX,&h0849
call interrupt &h21

Thanks for help.

Han
