Displaying specific columns in a file

Hi, I'm just wondering how you display a specific set of columns of a specified file in Unix. For example, if you had an AddressBook file that stores the Names, Phone numbers, and Addresses of people the user entered in the following format (the numbers are just to give an idea of what column number each field starts and ends in, they are not actually part of the file);
012345678901234568901234567890123456789
Name Phone Number Address

How would the user go about displaying only the phone numbers of the file?

FSLSFONTS(1)                                                  General Commands Manual                                                 FSLSFONTS(1)

NAME
fslsfonts - list fonts served by X font server SYNOPSIS
fslsfonts [-options ...] [-fn pattern] DESCRIPTION
fslsfonts lists the fonts that match the given pattern. The wildcard character "*" may be used to match any sequence of characters (including none), and "?" to match any single character. If no pattern is given, "*" is assumed. The "*" and "?" characters must be quoted to prevent them from being expanded by the shell. OPTIONS
-server servername This option specifies the X font server to contact. servername must be specified in one of the formats defined in the Font Server Names section of X(7). If not specified, the server name in the FONTSERVER environment variable is used. -l Lists some attributes of the font on one line in addition to its name. -ll Lists font properties in addition to -l output. -lll Supported for compatibility with xlsfonts, but output is the same as for -ll. -m This option indicates that long listings should also print the minimum and maximum bounds of each font. -C This option indicates that listings should use multiple columns. This is the same as -n 0. -1 This option indicates that listings should use a single column. This is the same as -n 1. -w width This option specifies the width in characters that should be used in figuring out how many columns to print. The default is 79. -n columns This option specifies the number of columns to use in displaying the output. The default is 0, which will attempt to fit as many columns of font names into the number of character specified by -w width. -u This option indicates that the output should be left unsorted. ENVIRONMENT
FONTSERVER To get the default fontserver. The server name must be specified in one of the formats defined in the Font Server Names section of X(7). SEE ALSO
xfs(1), showfont(1), xlsfonts(1), X(7). BUGS
Doing ``fslsfonts -l'' can tie up your server for a very long time. This is really a bug with single-threaded non-preemptable servers, not with this program. AUTHOR
