Delete new line characters from a file

Hi,

I have a file with about 25 colums separated with '~', but few of the lines have extra tabs ('^') and new line characters ('$'). Is there a way I can delete those characters if they are anywhere before the 25th column in a line?

example:

Code:
CLUB000650;12345678;0087788667;NOOP MEMBER                   ;Sam          ;Sam         ;31 bridge Rd.$
ABCD00001111;PQRS20393343;0088518295;NORTH AMERICAN DIRECTORY SERV.;TATE;HELLO;123 MAIN STREET;;;LOVELAND;CO;80538;Tate  HELLO                ;11 STREET^I       ;                              ;                              ;LOVELAND                      ;CO;80538         ;N TON 00477      ;                                                  ;BLK 9K #C90A FHP MEDIA  ;S1741721;2005-06-08 00:00:00;135;1;119.52;0$

Thanks

cat(1)							      General Commands Manual							    cat(1)

Name
       cat - concatenate and print data

Syntax
       cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...

Description
       The  command reads each file in sequence and displays it on the standard output.  Therefore, to display the file on the standard output you
       type:
       cat file
       To concatenate two files and place the result on the third you type:
       cat file1 file2 > file3
       To concatenate two files and append them to a third you type:
       cat file1 file2 >> file3
       If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file.  Output is buffered in
       1024-byte blocks unless the standard output is a terminal, in which case it is line buffered.  The utility supports the processing of 8-bit
       characters.

Options
       -b   Ignores blank lines and precedes each output line with its line number.

       -e   Displays a dollar sign ($) at the end of each output line.

       -n   Precedes all output lines (including blank lines) with line numbers.

       -s   Squeezes adjacent blank lines from output and single spaces output.

       -t   Displays non-printing characters (including tabs) in output.  In addition to those representations used with the -v  option,  all  tab
	    characters are displayed as ^I.

       -u   Unbuffers output.

       -v   Displays  non-printing  characters (excluding tabs and newline) as the ^x.	If the character is in the range octal 0177 to octal 0241,
	    it is displayed as M-x. The delete character (octal 0177) displays as ^?.  For example, is displayed as ^X.
