+# ---------- REVERSE Bubble Sort Algorithm
+# Python implementation of bubble sort algorithm
+# uses the csv, and inputoutput modules to import
+# CSVs and sort the numbers in a list before writing
+# to a CSV file with an appended -sorted title.
+
+# ---------- Imported modules
+import inputoutput as io
+import csv
+import sys
+
+
+# ---------- Main
+target = sys.argv[1]
+
+# ingress of data
+numdata = io.ingressCSV(target)
+
+# bubble sort operation
+for i in range(len(numdata)):
+        for j in range(0,len(numdata)-i-1):
+            if numdata[j] < numdata[j+1]: #FIXME: flipped comparative op
+                numdata[j], numdata[j+1] = numdata[j+1], numdata[j]
+
+# finishing up, appending "-bubblesorted" to CSV
+target = target[:-4]+"-REV-bubblesorted"+target[-4:]
+print("Sorting complete! Writing to file.")
