Hi,
    
This is untested but should be close to what you need.
    
R E B O L []
word-list: parse read %file.txt none ; read the file file.txt then use parse to break the strings into a block
word: first random word-list ;pick a random string from the block
alert word ; display the word in an alert window
    
Cheers,
John
