# FXFCACHE.COM -- Named common block used to cache filenames and image

# ##### This should be reimplemented to use a small package (i.e. functions)
# ##### rather than global common.  rf_fname below is using a lot of memory.
# ##### Dynamic memory allocation or a packed string buffer should be used
# ##### instead.  Not worth fixing though until the cache code is redone.
