3511.0. "opcode reserved to DIGITAL fault at PC=0002EB72" by OSLACT::SIGURDA_P () Tue Nov 09 1993 11:17

This error message appears when a customer tries to access an image from
ALL-IN-1, using the follwing command:  $run 'image'

<spawn run 'image' works fine.
I can do a $run oa$lib:mailcount inhouse, with no errors.

My customer is also very interested in knowing exactly what is the difference
between <spawn and $.  

$ does not create a sub process, right? So, you do not have to set process count
>1?


The stack dump is attached below.


Thanks,

Sigurd.

	Sigurd, <SPAWN creates a sub-process with SYS$INPUT and SYS$OUTPUT pointing to your terminal, but $ has them pointing to a VMS mailbox (in EXEC mode) and the terminal (in SUPER mode). There are many IO calls that cannot be used on VMS mailboxes, so if your image is trying to user one then something is going to break!
