SECOND SCRIPT. still contains original errors. Suggested changes in red.
Code:
#!/bin/ksh
#################################################################################
# This script uses grep and gets the working copy locations from the dnaRelowc1.dat file                            #
# and creates a script with the relocate command to relocate DNA build working copies from                      #
# the  svn01g.gdc.net server to the svnprod.nwie.net server.                                                                                #
#################################################################################
#
# Read the list of Subversion working copies directories to Relocate to new Subversion Server
OutputLoc="/scripts/dataout"
bldDirLoc="/webdata/tmpDNAbld/"
wcfiles=${OutputLoc}/dnaRelwc2.dat  
svnRelcmd="svn relocate"
set svnRelcmd

cd ${bldDirLoc}

cat "${wcfiles}" | while read i
do
    #get current host URL from each entries file
    OldRepo=`grep svn01g.gdc ${i}/.svn/entries | tail -1`
    #Replace each current host URL with New host URL
    NewRepo=`grep svn01g.gdc ${i}/.svn/entries | tail -1 | sed '/svn01g.gdc/ s/svn01g.gdc/svnprod/g' | sed 's/\/svn01p//g' | sed 's/\/Repositories//g'`
    #print line to change directory to each directory that contains the .svn(dotsvn) subdirectory (cd PATH)
    echo "cd $i"
    #print next line to execute command in each directory (svn relocate OldRepo NewRepo)
    echo "$svnRelcmd $OldRepo $NewRepo"
done

Apart from the form-feed characters which show as "\f" the input file looks ok.
The overwriting on the screen was caused by the "\c" in the "echo -e".

pmdiscoverservices

PMDISCOVERSERVICES(3)					     Library Functions Manual					     PMDISCOVERSERVICES(3)

NAME

       pmDiscoverServices - discover PCP services on the network

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmDiscoverServices(const char *service, const char *mechanism, char ***urls);

       cc ... -lpcp

DESCRIPTION

       Given  a  PCP service name, as identified by service, and using the type of discovery optionally specified in mechanism, pmDiscoverServices
       returns, via urls, a list of URLs representing the services discovered on the network.

       service specifies the PCP service to be discovered. Currently,  only  PM_SERVER_SERVICE_SPEC  is  supported,  which  searches  for  pmcd(1)
       servers.

       mechanism  specifies  the  style of discovery to be used. Currently, only "avahi" is supported. This searches for services which are broad-
       casting using mDNS via avahi-daemon(8).	mechanism may also be NULL, which means to use all available discovery mechanisms.

       Normally, pmDiscoverServices will return the number of services discovered, else a value less than zero for an error.  The value zero indi-
       cates that no services were discovered.

       The  resulting list of pointers, urls, and the values (the URLs) that the pointers reference will have been allocated by pmDiscoverServices
       with a single call to malloc(3C), and it is the responsibility of the pmDiscoverServices caller to free(urls) to release the space when	it
       is no longer required.

       When  an  error	occurs,  or no services are discovered, urls is undefined (no space will have been allocated, and so calling free(3C) is a
       singularly bad idea).

PCP ENVIRONMENT

       Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP.  On  each	installation,  the
       file  /etc/pcp.conf contains the local values for these variables.  The $PCP_CONF variable may be used to specify an alternative configura-
       tion file, as described in pcp.conf(5).	Values for these variables may be obtained programmatically using the pmGetConfig(3) function.

DIAGNOSTICS

       EOPNOTSUPP
	      The specified mechanism is not supported.
