SYNOPSIS

function csv(g1,g2,g3,..g20)

   class(*),intent(in),optional           :: g1, g2, g3, g4, g5, g6, g7, g8, g9, g10
                                          &  g11,g12,g13,g14,g15,g16,g17,g18,g19,g20
   character,len=(:),allocatable          :: csv

DESCRIPTION

csv(3f) builds a CSV string from up to twenty scalar values or an array.
Although it will often work, using csv(3f) in an I/O statement is not recommended as the csv(3f) routine might generate error messages; and Fortran does not (yet) support recursive I/O.

OPTIONS

g[1-20]
optional values to print the value of. May be of type INTEGER, LOGICAL, REAL, DOUBLEPRECISION, COMPLEX, or CHARACTER.

RETURNS

csv a string in CSV (Comma-Separated Values) format representing the input values

EXAMPLES

Sample program:

   program demo_csv
   use M_csv, only : csv
   implicit none
   character(len=:),allocatable :: pr

      write(*,*)’LIST-DIRECTED:’
      write(*,*,DELIM=’QUOTE’)’string’,.true.,.false.,111,23.45,10.20e15,3456.78901234d0,cmplx(huge(0.0),tiny(0.0))

      write(*,*)’G0:’
      write(*,’(*(g0:","))’)’string’,.true.,.false.,111,23.45,10.20e15,3456.78901234d0,cmplx(huge(0.0),tiny(0.0))

      write(*,*)’CSV:’
      pr=csv(’string’,.true.,.false.,111,23.45,10.20e15,3456.78901234d0,cmplx(huge(0.0),tiny(0.0)) )
      write(*,’(a)’)pr

   end program demo_csv
