Hi There.
I have this piece of code which I call with the following; array.csh "one"
"two" "three four" "five" "sic cod"
#!/opt/perl-5.6.1/bin/perl -w
$count=0;
print " ARGV $#ARGV\n\n";
while (<$ARGV>) {
print "count $count $ARGV[$count]\n";
$count++;
}
I get the following output:
ARGV 4
count 0 one
count 1 two
count 2 three four
count 3 five
count 4 sic cod
Use of uninitialized value in concatenation (.) or string at array.csh line
9.
count 5
Use of uninitialized value in concatenation (.) or string at array.csh line
9.
count 6
Why does the the while loop keep going and not stop? It does stop if I take
the -w out.
I can get it to work like this;
$count=0;
$total = $#ARGV;
while ( $count <= $total ) {
print "count $count $ARGV[$count]\n";
$count++;
}
Could someone tell me the best way. I assumed the first option would be the
best but it does not work.
Thanks
Angus
