A documented new feature of HELP,/STRUCTURE in IDL 8.0 has caused me
a minor annoyance: According to the online help:
"If a single argument is provided to HELP, and it is a structure,
then HELP will automatically display the structure information without
having to set the /STRUCTURE keyword."
But I think this means that I can no longer use HELP to determine
the number of elements in a structure array. In IDL 7.1 I could
write
IDL> print,!version
{ x86 linux unix linux 7.1.1 Aug 19 2009 32 64}
IDL> help,tab
TAB STRUCT = -> <Anonymous> Array[58]
to determine that it has 58 elements. But in IDL 8.0, I get
information about the structure but no information about the number of
elements it contains... I have to print,N_Elements(tab) . --Wayne
IDL> print,!version
{ x86 linux unix linux 8.0 Jun 18 2010 32 64}
IDL> help,tab
** Structure <a065d74>, 21 tags, length=168, data length=162, refs=1:
OBS_ID STRING '00031688021 '
EXTNAME STRING 'uu297081092I '
ASPCORR INT 0
FILTER STRING 'U '
TSTART DOUBLE 2.9708109e+08

This explains why structure=0 works for me.

s = create_struct('a', 1, 'b', 'xxx')
help, s
help, s, structure=0
