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

DESCRIPTION

       This tool is able to communicate with Retrace server: create a new task, ask about task's status, download log or backtrace of a finished
       task.
