Hi again!
I hope that a little shell script will do the thing for you.
1.) Create the following BASH-Script
#!/bin/bash
export CUSTNO=""
export CUSTNO=$(awk -F"," '{print NR " " $3}' datafile.csv | grep 1 | cut -d" " -f2)
sed -i 's/#x#/'$CUSTNO'/g' controlfile.datI've use datafile.csv as the name of the datafile to load and controlfile.dat as the name of your controlfile. Please change this to fit your needs.
This script looks for the occurrence of your constant value and stores this value in the variable CUSTNO. Then it look for a string #x# in your controlfile and changes #x# to the value of CUSTNO.
So in your controlfile there should be a line for custno like that:
custno                     CONSTANT '#x#'This line will be replace in your example to:
custno                     CONSTANT '35642'To get this to work I assume that:
1.) Your constant value is always at the third position in the header of your datafile.
2.) You've made the change with #x# in your controlfile.
I hope that this is really usefull to you.
Best Regards
