Hi all,
Just a quick question and a couple of lines of really simple code....
use Getopt::Long;
...
GetOptions ('h' => \$h,
'b=s' => \$s );
Sub ShowHelp() {
print "this is help"
}
Sub DoSomethingWithString() {
...
}
If ($s) {
DoSomethingWithString();
} else {
ShowHelp();
}
Right. Now, whilst the above is not perhaps 100% correct, it goes about a
generality of Getopt::Long.
If I now run the application,
./blah.pl -h - I get the help screen
./blah.pl -s - I get a error, complaining that -s requires a value, and
THEN the help screen.
./blah.pl -s s - Everything is fine.
So, this is more of a block question I think, but how I can get the above
example to show the help screen FIRST, and THEN complain about the missing
value for -s ????
Thanks,

Chris.
