I still would like to see it being fixed. In my case i can only do that because i know that i only execute a specific tos program.

It does not matter what method is used. The arguments are passed to tw-call, which writes them to a shared memory area, then tells toswin to fetch them. It is toswin which is building a new commandline from this to execute the actual program, and there the arguments are not quoted when they fit in the 126 byte limit.

Its only used when the program runs as acessory on SingleTOS. You can't use Pexec() from accessories in this case.

Of course I disagree for shel_write but too lazy to explain ;)

Using ARGV should not produce any white-space-problems (I added them to 
the arguments in the caller).

I don't know what you want to achieve but I use spawn() from the mintlib 
for example, but a simple Pexec should also work.
