The HDF_VD_FDEFINE procedure adds a new field specification for a VData in an HDF file. HDF_VD_FDEFINE can only be used for a new VData.
HDF_VD_FDEFINE, VData, Fieldname [, /BYTE | , /DOUBLE | , /FLOAT | , /INT | , /LONG] [, ORDER=value] [, /UINT] [, /ULONG]
The VData handle returned by a previous call to HDF_VD_ATTACH.
A string containing the new field name.
Set this keyword to indicate that the field will contain 8-bit unsigned integer data.
Set this keyword to indicate that the field will contain 64-bit floating point data.
Set this keyword to indicate that the field will contain 32-bit floating point data.
Set this keyword to indicate that the field will contain 16-bit integer data.
Set this keyword to indicate that the field will contain 32-bit integer data.
This keyword specifies the number of distinct components in the new field. Compound variables have an order greater than 1. The default order is 1.
Set this keyword to indicate that the field will contain 16-bit unsigned integer data.
Set this keyword to indicate that the field will contain 32-bit unsigned integer data.
