I would not recommend using "Perl Format" for this.
I think printf/sprintf is the way to go.
To get you started, here is some simple example code:
use strict;
use warnings;
my @vals = (
[ "hello there", 9, 7, 42, 3.14159 ],
[ "another string", 12, 9, 123, 69.123 ],
);
for my $r (@vals) {
printf "%-20.20s %02d:%02d %5d %8.4f\n",
$r->[0], $r->[1], $r->[2], $r->[3], $r->[4];
}
Running this program produces:
hello there 09:07 42 3.1416
another string 12:09 123 69.1230
Please post the sprintf code you tried,
explaining why it did not work and we should be
able to help you.
