Passing command-line arguments to Tcl

Passing command-line arguments to Tcl

Is there any way to pass command-line arguments to a script?

For example, I am writing a parsing program and would like to specify the settings.
I don't want to delve into creating and reading values from checkbox, radio button, or text widgets, etc.
in Tk if I don't have to do it.

The simple solution to me would be to use the command-line. But, I don't know if Tcl allows you to
use the command-line. For example, I would call my parser to print all the procedures in a Tcl script:

RE: Passing command-line arguments to Tcl

The command line arguments are available inside a script
as global variables:

argv0 is the name of the script
argv is a list of the arguments
argc is the number of arguments
(equal to [llength $argv])

Hence the following script should print out the arguments:

# The next line runs tclsh, passing the \
# arguments of this shell script to it. \
exec tclsh "$0" "$@"

puts "Command line arguments: $argv ($argc)"
