<DIV><FONT face=Arial size=2>This is quite maddening. I am using IDL 5.2 and am
working with HDF files. Consider an array with 2 columns, where each col is a
field and each row a record. In the language of HDF, that would be a VDATA. In
theory, then the following commands should work:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>fid=HDF_OPEN('test.hdf',/CREATE)</FONT></DIV>
<DIV><FONT face=Arial size=2>Vdat2 = HDF_VD_ATTACH(fid, -1, /WRITE)</FONT></DIV>
<DIV><FONT face=Arial size=2>HDF_VD_WRITE, Vdat2, 'F1,F2',
fltarr(2,10)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>But I get the error</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>HDF_VD_WRITE: Unable to set the VDATA fieldnames to
<STRING ('F1,F2')></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>

<DIV><FONT face=Arial size=2>I just simply cannot make it write more than one
field name!</FONT></DIV>
