how to create a file

[bdale16]

I want a perl program when executed to send the data to a file such as  text.txt but i 
dont need to open the file first.
 apparently i don't understand what the command is to  do this 

 If it is  open close or write ?
 any suggestions on the right command to use and the yntex so i can  experiment with 
saving data created in pearl programs to files
