Restriction on input data

Currently PISAFIND works with INTEGER data in the range 0 to 32766. An array of real data in this range will be accepted by the routine but the following message will appear:
   Input NDF is of type _REAL - this application can only process at
   _WORD precision; significance may be lost
If the array contains data outside this range the program will abort with the following message:
   ! The input NDF contains "bad" pixels or values outside the range of
     _WORD, these cannot be correctly handled by this application.

A previous restriction on the size of the input data has been removed, however, other limitations still apply. The maximum length of the first dimension of any input data is 10240 pixels. Objects cannot fragment into more than 200 pieces.
