Hello,
           I am trying to add a dimension(limited) to an existing necdf
file and I am getting this error -

NetCDF : String match to name in use

Following is my code in Fortran

 retval = nf_open(in_cfn,NF_WRITE,ncid)
if (retval .ne. nf_noerr) call handle_err(retval)
 retval = nf_redef(ncid)
 if (retval .ne. nf_noerr) call handle_err(retval)
 retval = nf_def_dim(ncid,"dimz_Z",len,dimz_zid)
 if (retval .ne. nf_noerr) call handle_err(retval)
 retval = nf_enddef(ncid)

This dimension "dimz_Z" does not exist in any of the .nc files in my
directory. There are no similar dimension names either. The other
dimensions are lat, lon, time and level.

Is there any obvious error in my code ?

Appreciate the suggestions,
Regards,
Ashwin.
