   AMP can handle a maximum of 16 label names.  If you find that you need
   more labels than this amount then you should use subscripted or indexed
   labels.  This is done by declaring such labels before using them.

   For example :

   	LABEL Q[1..40]

   could be a label for 40 different equations with the same label name,
   "Q".  Labels could then be declared as follows :

   þQ[1] : a = b
   þQ[2] : c = d
   .
   .
   .
   etc.
