[list exec "explorer.exe /root,$qpl(data)"]

couldn't execute "explorer.exe \root,L:\bc246t\data": no such file or
directory
"exec {explorer.exe /root,L:/bc246t/data} &"

I have tried to use \/root with the same problems.

What is the easiest way to avoid this error in tcl/tk 8.4 in windows 98
and above.

TIA.

THE EXEC COMMAND TAKES A BUNCH OF ARGS, NOT A SINGLE STRING!

This seems to be a *frequent* newbie error.

If necessary, eval (8.4) or the '*' notation (8.5+) is your friend:

eval [list exec "explorer.exe" "/root,$qpl(data)"] &

Well here is what I had to do in tcl 8.4 to get it to work. I had tried
the eval earlier but left out curly brackets:

regsub -all {/} $qpl(data) {\\} qpl(rf)
pack [button $gx.a.2 -text "View in Explorer" -command {eval [list exec
"explorer.exe" "/e,/root,$qpl(rf)" &]}] -side top -anchor n} \

Why use 'eval' here?
Why does
... -command [list exec "explorer.exe" "/e,/root,$qpl(rf)" &] ...
not work?

I don't know what Keith originally wanted to do. Most of the time
people do things like create command strings (instead of just calling
exec with the bunch of arguments), they are building up the command line
some how. Building it up with append (or inlined string building) does
not work, one needs to use lappend or list. The result needs to be
'flattened' as an argument *list* to exec and the easiest was to do that
is with eval. I was just giving the typical tcl idiom for doing this.

It would work just fine, if that was what Keith was doing.

... -command [list exec "explorer.exe /e,/root,$qpl(rf)" &] ...

does NOT work...
