Standard POSIX parameter expansions do everything you seem to want here:
Code:
#!/bin/ksh
while read base e1 e2
do	touch "${base%.*}${e1:+.$e1}${e2:+.$e2}.finished"
done < ListFile.txt

${base%.*} will remove the last period and everything following it from the 1st word on a line in the input file. ${e1:+.$e1} expands to an empty string if the 2nd word on a line from the input file was not present or to a period followed by that word if it was present. ${e2:+.$e2} does the same thing for the 3rd word.

With the ListFile.txt from the first message in this thread, this script will create (or update the timestamps to the current time if they already exist) the files:
Code:
test1.finished
test2.PC1.finished
test3.PC2.PC21.finished
test4.finished
test5.PC3.finished
test6.PC4.PC41.finished

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
