Free Format Input
-----------------
In this version of NEC, unlike that described in the manual the fixed
`punch-card' style input has been relaxed and quantities can be
specified according to the following rules.
1) First two columns must contain the type of CARD e.g. CE
2) Subsequent columns must be separated by either, at least
one blank space, or a comma.
3) Scientific notation can be used for specifiying REAL
valued quanties.
4) Decimal points may be omitted or used as desired. For example
(Integer Expected) 3232. translates to 3232
(Real Expected) 1213 translates to 1213.
(Real Expected) 12E-3 translates to 12.E-3
Extra Cards
-----------
This version of NEC contains some extensions over and above the
card input officially documented.
1) Spiral
A helix input card GH where the helical length HL is set
to zero will implement a spiral.
