Take following FB syntax:

  dim X as UniChar
  long if ( X > 0 ) and ( X < 100 )
  ...
  end if


The FBtoC translator produces:

  UniChar X;
  if ( (-(X > 0)) & ( -(X < 100) )  )
  {
  ...
  }


Could somebody please explain the "-" minus sign in this situation? Or
should it simply be amended by hand to say:

  UniChar X;
  if ( ( X > 0 ) && ( X < 100 ) )
  {
  ...
  }


Have read about ObjectiveC and the "methods" which is denoted using the "-"
minus sign but cannot understand the meaning in the above line? Do not fully
understand ObjectiveC syntax as yet, but this minus sign is really
confusing.

Any hints would be appreciated.
