!     rules for parameter constants

!     use prefix of "c" for whole real numbers (eg: c57 for 57.0)
!     use "m" after prefix to designate negative values (minus sign)
!       (eg: cm7 for -7.0)
!     use prefix of "p" for non repeating fractions (eg: p5 for 0.5)
!     use prefix of "r" for reciprocals (eg: r3 for 1/3.0)
!     combine use of prefix above and "e" for scientific notation, with
!       (eg: c5e4 for 5.0e4, c1em10 for 1.0e-10)
