// At compile time, define: WITHF77UNPACKER

// and F77NPARAMS to be the maximum number of parameters the Fortran

// unpacker will fill in.

// In the unpacker, set FPARAMETERS(i) if i has been unpacked from

// the event.

// PARAMETERS are copied from 1 -> NUSED into parameters numbered

// NOFFSET -> NUSED+NOFFSET

// NOFFSET starts from zero.

// The fortran program should be compiled:

// cpp -DF77NPARAMS=nnnn yourprog.f > yourprog.for

// f77 -c yourprog.for

// rm yourprog.for

// Assuming you’ve writtne the file yourprog.f
