Code:
sed "32,45s/[()]//g" file

This line will delete all parenthesis that are in "file"
from line 32 to line 45 (included), and this will be done globally
(so all occurrence in the line will be deleted even if there are more
than 1 parenthesis per line (where 32 <= linenumber <= 45)

Code:
sed "s/\([0-9]\)-\([0-9]\)/\1\2/g" file

this line will suppress all minus sign that are in between 2 figures

Code:
$ cat myt
I[()]A
321-432 654-9879 6754-6564 -
$ sed "s/[()]//g" myt
I[]A
321-432 654-9879 6754-6564 -
$ sed "s/\([0-9]\)-\([0-9]\)/\1\2/g" myt
I[()]A
321432 6549879 67546564 -

NAME

       viewperl - quickly view syntax highlighted Perl code

SYNOPSIS

       viewperl [OPTION]... FILE...

DESCRIPTION

       View a Perl source code file, syntax highlighted.

       -c, --code=CODE
	      view CODE, syntax highlighted

       -l, --lines
	      display line numbers

       -L, --no-lines
	      supress display of line numbers (default)

       -m, --module=FILE
	      consider FILE the name of a module, not a file name

       -n, --name
	      display the name of each file (default)

       -N, --no-name
	      supress display of file names (implied by --no-reset)

       -p, --pod
	      display inline POD documentation (default)

       -P, --no-pod
	      hide POD documentation (line numbers still increment)

       -r, --reset
	      reset formatting and line numbers each file (default)

       -T, --no-tabs
	      supress translating of tabs into spaces

       --help display this help and exit

       Note that module names should be given as they would appear after a Perl `use' or `require' statement.  `Getopt::Long', for example.

       Each string given using -c is considered a different file, so line number and formatting resets will apply.
