 TEST The coordinates are those given in the paper but the atomic 
      distances do not agree with those calculated during testing. The 
      coordinates are probably correct. (Code 76)
 TEST A site occupation is implausible or meaningless but agrees with 
      the paper. (Code 54)
 TEST Difference between the formula calculated from the PARM record and 
      the FORM record tolerable. (Code 21)
