With Microsoft word, just replace A with A (etc) and look at the bottom
left hand corner of the window for how many replacements it made. 

However, I recommend:

Seqspeak 1.0 will figure base compositions as well read your sequences
back to you (with many options as to speed, etc).  It has some bugs so if
you want to use it more extensively write me for a help sheet.  It is
freeware and available from via fetch, ftp, gopher or
www (thanks to Don Gilbert!).
