Description


              The type of the parameter being restrained.

               Explicit sets of data values are provided for the programs
               PROTIN/PROLSQ (beginning with p_) and RESTRAIN (beginning with
               RESTRAIN_). As computer programs will evolve, these data values
               are given as examples, and not as an enumeration list. Computer
               programs converting a data block to a refinement table will
               expect the exact form of the data values given here to be used.
