Title: startup-seq
Post by: lionstorm on February 13, 2004, 07:46:20 AM

Hi all,
I added buffers to some drives on my startup-sequence but if drive is missing, I get the message can not find device and have to press retry or cancel.
ex : addbuffers df1: 50
But how to avoid this message and let the s-s go on when the df1 is disconnected ? How to tell the system "well if the device is not there just forget" instead of "well the device is not there, what should I do : ask the guy who switch me on" ?

Hi, lio!

Try the following:

assign >NIL: DF1: exists
IF NOT WARN
    ADDBUFFERS >NIL: DF1: 50
ENDIF

Thanks, it looks good.
what the >NIL: is supposed to do ? (I am no developper)

The ">" sign redirects the output to the file following the sign. NIL: is the AmigaDOS trashcan, it trashes everything written to it.

So if the addbuffers command does not stop the script the addition of ">NIL:" to the command will be sufficient. You may also add the line

failat 21

to the top of the script so it will bever be stopped by a failing command. (Failat sets the smallest return code which will stop the script. And a failing command usually returns 20.)

Bye,
Thomas

Thanks Thomas for sharing this. So I should put the failat 21 before the assign ?

I use failat 21 on the top of startup scripts, so they do not freeze even if I forget to remove obsolete lines from them...

That's akin to painting over rising damp, really though... I never used a failat in five years of constant (and I mean constant) Amiga use. It's better to know if something's going wrong.

Yeah, you do know when using RTG screenmode you get black screen by startup and begin to change monitor/lead/boot partition etc etc. to see what's happening...
