I think you can't use repeat like this as it doesn't return the value you want.
But insert/dup should be your friend here :
write/append/lines %output.txt insert/dup copy "" "*" nb ; with "nb" the number of
*
If you want to produce the graphic above, consider generating the line before adding
it to the file :
nb: 4
line: copy "2pm : "
insert/dup line "*" nb
write/append/line %output.txt line
