Hi,
I missed to add a very important detail to my previous e-mail. As the sizes of ms_data(1)%biomass(
and ms_data(1)%mortality( are not equal; also the sizes of ms_data(1)%biomass( and ms_data(2)%biomass( are not equal.
Regards,
Ekin

Hi,
Please let me put it this way. I have a user-defined type in FORTRAN called "ep_data" of dimension 4, i.e. ep_data(4). It has fields named biomass, pob, qob, ... etc. and so on. Each field holds a scalar value. For instance, if you print "ep_data(1)%biomass", it will give you, let's say, "4". In other words, fields of "ep_data" are not arrays. I succeeded to write this "ep_data" to HDF5 by using compound datatype. So no problem up till here. However, I have another user-defined type called "ms_data" in FORTRAN of size 7, i.e. , "ms_data(7)" and just like "ep_data", it also has fields named biomass, mortality, qob, ... etc. and so on. Differently from "ep_data" type, "ms_data" fields are arrays of different size. For instance, if you print "ms_data(1)%biomass(:)"|, you will get an array of real numbers. And if you print "ms_data(1)%mortality(:)", you also get an array of real numbers of different length that of "biomass" field. So, how can I store "ms_data" in HDF5 format?
For your reference, my FORTRAN implementation of storing "ep_data" is attached.

Ekin

Hello,
I am sorry that I could not make myself clear. What I meant to say is that I aim to form a compound datatype which comprises VL (variable length) and fixed-length array fields/datatypes. In the example for creating VL datatype, using a user-defined datatype which includes a pointer is suggested (Example 27 on page 227 in the HDF user manual). That is what I want to avoid but it seems it is the only way. What I want to achieve is summarized in Figure 18 on page 238 in the HDF user manual; a compound datatype built up of numerous VL and atomic datatypes.

Hi,
suggestions about storing this data as a compound type with variable
length fields without using pointers as explained in
h5ex_t_vlen_F03.f90 [1] example script on HDF GROUP web site. Thank
you in advance for your concerns.I don't understand what you mean by "not using pointers", do you mean you don't want to use C_LOC and/or F2003 and still do the same thing as h5ex_t_vlen_F03.f90? Can you explain further what in h5ex_t_vlen_F03.f90 you want to avoid doing?
