Re: Problem passing parms to spawned job

Hi Jairo,

You're right, parameters  via spawn() won't pass properly if they have 
embedded nulls.  This is because spawn() is modeled after the tools used 
on Unix systems, which only allow text parameters, and use 
null-terminated strings.

Consider connecting a pipe or data queue to the spawned job, and passing 
the data to the new job that way.  That should eliminate the problem.

Or if you really like parameters, use cvthc() to get a hex dump of the 
parameter (which will be all text), pass it, and use cvtch() to convert 
it back on the other end.

Either alternative should do the job.
