A variation in which you can enter the output filename as a paremeter.
#macro Write_something (file_name,N)
#fopen F file_name write
#write (F,N)
#fclose F
#end
Write_something ("test.txt","Hello, world.\n")
By the way, is there a powerful and unavoidable reason to introduce as a
parameter the id_file handler?
