In fortPre1 (file:newfort.boot.pamphlet)
fortPre1 e ==
-- replace spad function names by Fortran equivalents
-- where appropriate, replace integers by floats
-- extract complex numbers
-- replace powers of %e by calls to EXP
-- replace x**2 by x*x etc.
-- replace ROOT by either SQRT or **(1./ ... )
-- replace N-ary by binary functions
-- strip the '%' character off objects like %pi etc..
