Lock file creates with '?'

Hi,

I am trying to create a lock file with the following code but for some reason after file is created it has
wrong name "PASP?.lock??"

Please let us know how to get rid of these '??' from file name and from where they are coming?

Code:

#!/bin/ksh
################################################################################
PGM_NAME='PASP'
LOCKFILE=/tmp/${PGM_NAME}.lock
################################################################################

if [ -e $LOCKFILE ] ; then 

    echo "data file does exist"

else 
   touch ${LOCKFILE}
   echo "new data file created"

fi

Thanks
Sandy
