Need help in making a script

Hi I am new to this forum. And pretty new to auto-it. My friend directed me to here for help.

I just want to know how to read from text file and write it according to the order.I want to modify the names in text file as according to my wish.Also no matter whenever i start the script it should start from the last name written until it ends. When it ends if i start the script again it is gonna start from word 1

Example text file.

word1,word2,word3

for word1 write dada,word2-asda etc.


Please help!
