Re: confused about lists and strings...

The name "args" is special in TCL returning all remaining arguments as a list.
As you call:
process1 $argv
The one argument is put in a list. The result is a matrix (list in list).
How to solve:
a) don't use "args":
proc process1 myargs {
       set first [lindex $myargs 0]
       puts "first='$first' args='$myargs' list? [string is list -strict $myargs]"
       set rest [lrange $myargs 1 end]
       puts "rest='$rest' list? [string is list -strict $rest]"
}
b) use the delist operator:
process {*}$argv
Hope this helps,
