Code:
#!/bin/ksh

# the name of a file to search
file='myTextFile.txt'

# a name to search
name='AIX17_JB'

# function - takes 1 input parameter - the 'name' to look up
getAddr() { # name

#   assign the 1-st [and only] parameter to a locala variable 'name'
 typeset name="$1"

#   call 'nawk' with the Field separator set to ';' and a local nawk variable 'name'
#   set to the value of shell variable '${name}'
 nawk -F';' -v name="${name}" '
     # if the 1-st field is of the same value as the variable 'name'... execute the block
   $1 == name { 
            # get the NEXT line
        getline; 
            # print the 1-st field
        print $1; 
             # exit this run of 'nawk'
        exit
   }' "${file}"
}

#     this is obvious - print out the 'name' to look up AND call the 
#     function 'getAddr' with the variable 'name' as its only parameter
echo "name->[${name}] address->[$(getAddr ${name})]"

pod::simple::dumpastext

Pod::Simple::DumpAsText(3)				User Contributed Perl Documentation				Pod::Simple::DumpAsText(3)

NAME

       Pod::Simple::DumpAsText -- dump Pod-parsing events as text

SYNOPSIS

	 perl -MPod::Simple::DumpAsText -e 
	  "exit Pod::Simple::DumpAsText->filter(shift)->any_errata_seen"

DESCRIPTION

       This class is for dumping, as text, the events gotten from parsing a Pod document.  This class is of interest to people writing Pod
       formatters based on Pod::Simple. It is useful for seeing exactly what events you get out of some Pod that you feed in.

       This is a subclass of Pod::Simple and inherits all its methods.
