Level 2 Help for F2COMP

Input file name
Up to two inputs

One output file name

The size field is specified with four arguments:
size=(sl,ss,nl,ns)

  F2COMP is a special purpose VICAR program to handle arithmetic
  operations on complex input data. It will take a most two input
  data sets.  The operations available are:
       ADD   (complex+complex, or complex+real)
       SUB   (complex-complex, or complex-real, or real-complex)
       MULT  (complex*complex, or complex*real, or real*complex)
       DIV   (complex/complex, or complex/real, or real/complex)
       CABS  (absolute value of complex input, output=real*4)
       CONJ  (complex conjugate of complex input, output=complex)
       COMP  (1st data set will be real, 2nds data set will be complex)
       REAL2COMPREAL
             (turns a real data set into a complex real data set)
       REAL2COMPIMAG
             (turns a real data set into a complex imaginary data set)
       COMP2REAL
             (extracts the real part of the complex data set and
              stores it as a real data set)
       COMP2IMAG
             (extracts the imaginary part of the complex data set
              and stores it as a real data set)

  This keyword, if specified along with div or mult option will
  perform a scalar division or multiplication instead of a
  complex operation.  Input data sets should be complex [*,/] real.

In mixed real and complex operations, the output will always be
COMPLEX*8. In mixed operations, real values are coverted to complex
with zero imaginary part before the operation is carried out.
Divide by zero protection is accomplished by setting the result
of an attempted divide-by-zero to zero on output.
