in reply to Reaped: print format

The best tool for formatting fixed length records is pack:

print pack 'A20 A10 A3', @$_ for (
[ qw[ Name DOB AGE ] ],
[ qw[ Name111111 010190 30  ] ],
[ qw[ Name222 020280 40 ] ],
);;

Name                DOB       AGE
Name111111          010190    30
Name222             020280    40

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
