SPUG: running script with the variables on the same line

[Medrano-Zaldivar, L E]

I really appreciate all your mails and actually I found code example of what I was looking for:
 
  

#!/usr/bin/perl
print "My name is $0 \n";
print "First arg is: $ARGV[0] \n";
print "Second arg is: $ARGV[1] \n";
print "Third arg is: $ARGV[2] \n";
$num = $#ARGV + 1; print "How many args? $num \n";
print "The full argument string was: @ARGV \n";

Now if you run this script, here's what you'll see:

$ ./testvars dogs can whistle
My name is testvars.pl
First arg is: dogs
Second arg is: can
Third arg is: whistle
How many args? 3
The full argument string was: dogs can whistle

Thanks,
Luis

Quite right; and it's interesting how my perceptual systems did
automatic error-correction on that! 8-}
