Export To Fixed Length File

I need to create a file from a query of an oracle table.
The output file needs to be structured in positions. Example,
from position 1 to 5 there must contain only those values, from 6 to 15 another field, 16 to 21 another field etc. This would be a 90 byte file. So there would be 90 characters for each line. After building the file, I need to send it to an emal address. Is there a way to do this? Please give me an example.

Thanks!

Fixed-length fields you can get in SQL*Plus by setting field formats and field separator or with SQL (PL/SQL) by using LPAD and RPAD functions and concatenating fields to one string.

Sending the email is another issue, depends on way you'd like to use and on your OS.
