natural language ? Sorry I was doing my best to communicate my needs.

the script will parse a file that has an unknown number of lines. Each line contains a column name. For eg file1 looks like this:
firstname
lastname
email
...
I will have a hardcoded string or two. say, "token__a", and "audit_action__a"

My final output from parsing that file will look like this:
..... insert into $table ( token__a, audit_action__a, firstname,lastname,email ) ....

Thanks,
floyd
