How to read a text file and assign the values in the same to a variable in loop

Hi,

I have a text file with multiple lines, each having data in the below format <DOB>,<ADDRESS>

I have to write a script which reads each line in the text file in loop, assign the values to these variables and do some further processing in it.

Using the following code prints the values but I need them in variables.Also, it reads only first line of the file.
cat filename | paste -d"," - - - | awk 'BEGIN{FS=","}{print "DOB="$1" ADDRESS="$2" }'
Am I wrong in my approach?

NAME
readfile, longline - reads file, gets longest line SYNOPSIS
readfile filename longline [filename] DESCRIPTION
The readfile function reads filename and copies it to stdout. No translation of NEWLINE is done. It keeps track of the longest line it reads and if there is a subsequent call to longline, the length of that line, including the NEWLINE character, is returned. The longline function returns the length, including the NEWLINE character, of the longest line in filename. If filename is not specified, it uses the file named in the last call to readfile. EXAMPLES
Example 1 Typical use of readfile and longline Here is a typical use of readfile and longline in a text frame definition file: . . . text="`readfile myfile`" columns=`longline` . . . ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
cat(1), attributes(5) DIAGNOSTICS
If filename does not exist, readfile will return FALSE (that is, the expression will have an error return). longline returns 0 if a readfile has not previously been issued. NOTES
More than one descriptor can call readfile in the same frame definition file. In text frames, if one of those calls is made from the text descriptor, then a subsequent use of longline will always get the longest line of the file read by the readfile associated with the text descriptor, even if it was not the most recent use of readfile.
