Here's my workaround:

---%<-----%<-----%<---[BEGIN CODE]---%<-----%<-----%<---
#macro Write_something (Filename, N)
   #fopen F Filename append
   #write (F, N)
   #fclose F
#end

#declare FILE1 = "test.txt"
#fopen F FILE1 write #fclose F //zero the output file
Write_something (FILE1, "Hello,\n")
Write_something (FILE1, "world.\n")
--->%----->%----->%----[END CODE]---->%----->%----->%---
