You will need to add 

MORE.FLAG = (MVDATA# "") again to just before the REPEAT, for the WHILE 
   To function properly, otherwise, it's just using the flag set prior
   To starting the LOOP

Use instead:
MORE.FLAG = (MVDATA # "")
LOOP WHILE MORE.FLAG DO
  SNGDATA = REMOVE(MVDATA, MORE.FLAG)
  ...
REPEAT
